Add the multiple identity check.
I think this was asked for more then once. Code was all ready written, used, works, and been around a long time. Not like it would be hard to make it a part of the message board as a standard release.
I had used it in the past but like others I got tired of hacking it into all the new releases and gave up on it as well as many other features that are on UBBDev and been used for quite some time.
