When signing up, it was pretty much a toss-up for me between my internet handle and the nickname I anticipate using on the playa. Unfortunately, the flipped coin favored the name nobody can spell and most can barely pronounce. Even though I genuinely like it as an identifier, I regretted choosing "ensimismada" before even my 10th post here.
So, I added the other nickname to my signature. That was easy.
Trilo, might I suggest a possible solution? I've seen other online boards put "formerly <old username>" or "AKA <old username>" under the current user name, right where yours says moderator. This might draw more attention to the fact that a name change is possible and thus make more work for the mods, but I think it would reduce confusion...

When he puts out his lamp, he sends the flower, or the star, to sleep.
That is a beautiful occupation.
