In the "What about open problems?" section of https://mathoverflow.net/help, the last line says "To join the discussion about how MathOverflow should deal with open problems, go to this meta.MO thread." However, there is no indication of which thread is referenced - neither a title of a thread nor a link. I suspect that it means What should be the policy on "open problems" on MO? (especially since the whole section seems copied from an answer there, and the link in that answer points to that thread again).
Edited to add: the entire help center seems to be lacking links present in the answers it is copied from (e.g. https://meta.mathoverflow.net/a/206), not just this one section, with the exception of the explanation of MO's corporate structure at the end.
