^Too bad you couldn't share a more thoughtful answer.

[quote=switpotato]if this will lead to confusion why not mandatory require the member
to display his old user name under his/ her quotation area
or siggy perhaps... or have some stamped like id that will stay for tym being[/quote]
I think this could be a good idea. And as I was saying previously, if we make this feature really hard to obtain, then I don't believe there will be too much confusion because I don't think many members are that concerned about their usernames and are not going to "strive" to attain a username change. I would bet that at least 50% of the members here are only here for the linkers. Those members don't care about changing their usernames.
Anyway, thanks again for all the feedback, whether positive or negative, I do appreciate it.
