While I am not opposed to the addition of this function in and of itself (unlike most of the other posters here, apparently), I do have to echo this point: I don't think it will find much use here.

The vast majority of FlyerTalkers seem to prefer to remain anonymous and not maintain any links between their FT identity and real world identity, unlike many other forums out there, where members' real names and locations are openly shared. While some of my coworkers know I participate here, they don't know my handle and so can't specifically pin me down to anything I might say here. And I think I've done a pretty good job of obfuscating links to my real name on FlyerTalk, at least in public view. I think most people are in a similar situation, and so a link between an anonymous username and your Real World identity (mandatory on Facebook) is really not something I'm interested in, despite using both heavily. I suspect most others are in the same boat.

But for those who would enjoy this functionality, I don't have any problems with having it here. And you can even leave the banner up for a day or two, but do pull it down once members have had a chance to see it--maybe leave a little "Connect" logo in the same area as the login details, but the full banner could get a bit obnoxious.
