I have a common account associated with 8 SEs, all linked through my Google OpenID. Apparently, the account I have with audio.stackexchange.com was created possibly using a different method, possibly even a different email address. I'm not quite sure - all I know is on StackExchange, when I review my accounts, I don't see that one in my list; when I'm in audio.stackexchange.com, I DO see that I have those other related accounts (which is odd). I have also tried using the "copy my profile" option, which didn't seem to resolve the issue.
I would hate to start over; I know that 85 rep seems like nothing to most of the luminaries here, but it means a lot to me! I would love to be able to just make sure that my audio.stackexchange.com account is properly linked with all my others.
