Looks interesting.
Is there any intelligence to detect if a user from another board already exists on the first board? So if Site A is participating with Site B, and user JohnDoe (with an email of
JohnDoe@SomeSite.com) already exists on both Site A & Site B, will his/her posts show up his real account on Site B after posting on Site A or will it still appear as a guest account named JohnDoe@SiteA?
