Hi – hopefully with the “remember me”, it won’t matter much that your email address is longer, and it would save us some complexity. We’ve already noted that several users want to ensure they can remain logged in to several different PCs simultaneously. And we’ve already included a Digg It!-style “this was useful” requirement and, related to that, a way of giving users status, so those who contribute a lot are recognised as such.
Oh, and I could have mentioned that we’re looking at the possibility of moving to the same software for both MyIOP and TalkPhysics. At the moment, MyIOP runs on Small World Labs (SWL). We may well end up running two different instances (i.e. we wouldn’t use the same underlying database), but at least it would simplify support for the two sites.
