Okay, maybe it's just me, but I don't see the link. Do you have to have a certain rep of your own to see it?
Oh, uh, oops. You do have to have a minimun number of posts to change people's reputations - otherwise people could just set up fake accounts and give themselves points.
I lowered the minimum to 10 posts so you should be seeing the links now.
As for name changing - I agree that it gets confusing. I'll have to figure out a way to close that off without people getting too mad.
