After having successfully played a character all the way through to its death, I have only one request to make to the DM and development team.

Is it possible to create a widget whereby we can change our own character descriptions? It would have been nice, throughout the development of my character, to give clues to the more subtle changes in the character to other players.

Currently, it's impossible. When there are very significant changes that occur to a character that actually need to be explained in the character description, sometimes we'll do them manually. For those othertimes, it's nice to have a bio that isn't completely set in stone!

Umm, on that matter, do DM's endorse the use of leto? Not saying that I would ask you to use it, but, you know, in case you want to change something important and all.

LETO is certainly used when an IC situation warrants a large change to a character. :)
