Since I manually associated my SO, SF, SU and MSO accounts months ago, Web Apps was my first experience with the automatic account association feature. It's nice, but I have a small nitpick: it copied over the name/OpenID/Gravatar I used on MSO, which is different than the ones I use on SO/SF/SU. As you have probably guessed by now, I wanted the SO/SF/SU name, OpenID and Gravatar. (Interestingly, when my Area 51 account was created, it did get my SO/SF/SU info, not my MSO info.) Is there a way to choose which account to use as the "primary" associated account, when an option is available?
(I wasn't sure whether to post this on Meta WebApps or Meta SO; it seems to apply equally to both. My story, if one becomes necessary, is that I'm providing an outlet to test the migration functionality.)
