Here’s a few words of advice on writing tag wiki excerpts: The excerpt is the elevator pitch for the tag. You only have ~500 plain text characters for the excerpt, so don’t feel obligated to cover everything in it! Save that for the 30,000+ character Markdown tag wiki. The excerpt should define the shared quality of questions containing this tag — ...

I support not re-starting manual deletions. The situation today with automatic deletion and no manual deletion is better than it used to be in the manual deletions era and it is also better to avoid practicing manual deletion on top of the automatic one. (On pupular request: update) As quid explained: "What does not get auto-deleted are closed questions ...

The title of the question mentions manual deletions, and Gil Kalai's answer voices his opposition to that. Let me answer quid's other concern: the system is currently automatically deleting some perfectly fine questions. I encourage 10k+ users to monitor the list of recently deleted questions, and vote to undelete reasonable questions that have slipped ...

The description of moderator tools is a bit short on details. Here is a slightly more detailed description of these tools. The relevant part is the following: The delete category has views relating to questions and answers that have been or are being deleted or undeleted: Most delete votes, sorted by number of votes Most undelete votes, sorted by number of ...

Yes, they can. -- See https://mathoverflow.net/help/privileges/moderator-tools.

No no, there is no link anymore. You go to "review" and then you should see "tools" somewhere on the top part of the page (below the top menu, though).

There are tags lattices and lattice-theory, both being used for the two unrelated meanings “partial order with binary suprema and infima” and “discrete subgroup of $\mathbb R^n$”. I’m not sure it’s feasible to sort out the ~300 questions involved, but maybe we could try at least to alleviate the problem for future by deciding which tag is supposed to denote ...

I suggest to rename the tag divisors in a way which distinguishes it more clearly from divisors-multiples. The tag-info for divisors (revision history) clearly says: For questions related to divisors in the sense of algebraic geometry (Cartier divisors, Weil divisors and so on). For question on divisors in the number theoretic sense please use the tag ...

Resolved: There is no longer kahler tag and we have kahler-manifolds tag. The new name for differential-graded-lie-a is now differential-graded-lie-algebras. (After the limit for tag names was increased to 35 characters.) Tag 'kahler': I was wondering if the tag 'kahler' should be renamed 'kahler-manifolds' (or something like it), so as to make it more ...

I have noticed that the tag duality is quite often used for questions about dual spaces in functional analysis and linear algebra. However, it's not immediately clear from the tag name that this is intended. (Although the current revision of the tag-excerpt explicitly mentions dual spaces.) In addition to that, duality is a word which is used in several ...

Maybe generalized-functions and schwartz-distributions should be made synonyms? I think technically the latter is a subset of the former, since the former can also cover Coloumbeau distributions.

Resolved: The tag synonym has been created. The tag history has been created a few days ago. This tag has been created a couple of times in the past and usually replaced by ho.history-overview. I think that the synonym history $\to$ ho.history-overview would be useful. If not for other reason, just to save the effort going into repeated removal of the tag.

Based on the reception of the question Pronunciation questions (currently at score 22) it seems that questions about pronunciation are on-topic on this site (within some reasonable limits). I suggest creating pronunciation tag for questions asking about pronunciation of mathematical terms, mathematical symbols and notation, names of mathematicians, etc. If ...

Resolved (The tag was created by Taras Banakh a few months ago, since then it has grown to 12 questions and nobody raised any objections to this tag.) I'd like to propose creation of continuum-theory tag. To me (as an outsider, but still a bit interested in this topic) it seems that continuum theory is an area of general topology which enjoys some interest ...

What about creating small-uncountable-cardinals tag? (The tag name is within the recently increased 35 character limit.) Looking at the main site, it seems that small uncountable cardinals (such as $\mathfrak p$, $\mathfrak t$, $\mathfrak b$, $\mathfrak d$, etc.) get quite a lot of attention on this site. For example, if you search for either of the ...

We have two tags called mathematical-software and software. The latter has currently empty tag-info and the tag-excerpt for mathematical-software currently says: Mathematical questions related to mathematical software systems such as Sage, Mathematica, Maple, Pari/GP, and GAP. Note that troubleshooting questions are generally considered off-topic. I ...

We have convexity tag - it has empty tag wiki, but I understand the tag broadly as stuff related to convexity, convex functions, convex sets, etc. (Of course, for some of such questions convex-analysis or convex-geometry are more suitable.) For some time there was concavity tag, see here. The tag was later deleted by an automated process which removed the ...

Resolved: Both the suggested tag and the suggested tag-synonym have been created. Maybe on-topic tag could be created on meta and made a synonym of allowed-questions. I think that it is quite probable that users asking about question which are on topic might look for a tag with a similar name. Several metas in SE network have a tag called (on-topic).
