So, if you have a character profile that needs editing, as some changes are needed, how do you go about changing the profile?
Do you mean in the Wiki or on the forums?
I would probably ask a GM if it was a good idea to do the change you are about to do, then make an account to the Wiki and do it.
If it's just a grammar change, leave the GM asking out.
Well, it's a major change. If everything goes as planned, then it changes at least three sections, if not more.
If you want to make major changes I suggest you re-write the passages you want changed and send them to Krilari/Piroska/whoever handles the Wiki, with an explanation to why you want it changed too.
Lesser changes you are free to do yourself cause they can see what you do on the Wiki and change it back if they don't approve.
