I don't know if i understand the whole concept to allow any user to create a name with "~" as the first character.. or even if it is necessary to allow that character to be in the user name at all?  Couldn't the forum software disallow the creation of usernames with such character, at least minimally as the first character?  Anyone know?  Loyce?

Seems misleading, as TMAN's red tag of "~DefaultTrust" suggests.
