keeveek: At least my nick is non scammable :P As long as you remember I have two "ees" on both sides :P
btw. I'm glad you improved PMs, GOG!
I think some names are stronger than others, but still, somebody could potentially have registered keavaek and caught somebody off guard that wasn't looking too closely, or has poor eyesight.
I think the only one for my nick is that rat fink hedvvards. Although i suppose that heolwards could potentially catch somebody that doesn't have good eyesight as well. But, I think really the worst letters are w and m for that sort of thing. It's rather tough to tell vv from w and rn from m sometimes, unless you look closely.
EDIT: A GM script to capitalize all letters in user names would probably help, since the usernames are apparently not case sensitive.
