This place has so many old User IDs hanging around that it's tough to find a good name when you register for the site. Everything is already taken!
And you can't do a search to find out what's available, until after you've already registered. It's a Catch-22. You have to just keep guessing at screen names until you hit upon something unused by luck.
Look at the screen capture, attached, for an example of the problem.

There's a whole bunch of IDs that people register with, but then never even bother to sign on, ever. And many others may have signed on at some point, but have a "last seen" date that is years ago, and have never posted anything.
These are dead accounts. You ought to clean them up. Free up some of those juicy User IDs for some new guys.
