Looking for a username management add-on for vB 3.6.x

[Pulsorock]

Hello,
I'm looking for an add-on that allows my users to change their username. I've been asked to change username from my users so many times, that I prefer to give them access to change their own, instead of I having to do it.

I would also like that this username management follow the rules I'd set in the AdminCP on illegal usernames and regular expressions on allowed characters for usernames.

I looked thru the forum, and all I could find was this add-on called Username Management, but it was for vB 3.5.x

Any suggestion is welcome...

Thanks!
