I was a stackoverflow user, and found this wonderful gaming site as a result. On SO, my account was an OpenID through my gmail address. When I made an account here, I was dumb and forgot that and made a normal account through my alias email (which has an alias name), which I tend to use for gaming purposes. I didn't think anything of it until it recently combined the two accounts automatically, which changed my name and re-awarded all my badges and Diablo III contest gems. I got rid of the alternate login through "my logins," and changed my name back, and I think I'm back to where I want to be. However, it says that I haven't participated in any tags. Did the database get all screwy when the accounts combined, or should I have taken different steps to un-link the accounts?
Edit: I posted this without having participated in any tags since the merge. Since then, I have answered a few more questions, and my tags still aren't showing up.
