Looking through meta-MO I have found a [proposal of Martin Sleziak][1] to create a new "small-uncountable-cardinals", which I liked since many of my (and not only my) questions fall under this tag. So, I created a new tag "small-uncountable-cardinal" and tagged several my question with this new tag till realized that I forgot to add "s" at the end of cardinals. So, I tried to create a new (and more correct) tag "small-uncountable-cardinals", but the system has blocked this attempt writing that a similar tag "small-uncountable-cardinal" exists already. So, I removed all tags "small-uncountable-cardinal" from my questions and now no question is tagged with "small-uncountable-cardinal", but still this tag exists in the system and does not allow me to create a new tag "small-uncountable-cardinals". According to rules of MO, a tag which is not used for 24 hours will disappear. This means that I can  hope to create the new tag "small-uncountable-cardinals" after 24 will pass. In the meantime I would like to ask the MO-community for opinion concerning the idea (basically of Martin Sleziak) to create this new tag "small-uncountable-cardinals" and retag the relevant questions (this last procedure is not accepted well by many MO users as it bumps up the retagged questions).

Search through MO by the phrase "small uncountable cardinal" yields 100 answers and I suggest that there are many questions which do not use this phrase but use small uncountable cardinals (like $\mathfrak b,\mathfrak p,\mathfrak d,\mathfrak c$, etc.). Do you this is a sufficient number for creating a tag or not?
