I don't understand why the fact that GN is a smaller community makes any difference to the facilities we have. If anything, the fact that we 'know' each other better makes the need for an occasional name change more likely. Why would someone confide a personal matter when it would be remembered for years?
Similarly, an edit button is no more likely to cause issues here than elsewhere - many of us post on MN too, and this who don't are not a separate species. If we can handle it over there, why is it assumed we can't on here? It's quite insulting to have two sister sites and deny members of one the things that the other gets as a matter of course - as has been said, nobody would have to use anything they didn't want to, so why can't we be offered the same facilities as on MN? We have often asked for OP posts to be highlighted for instance, or for a better search facility, but we are always ignored.
