I'd bet you havent looked at all the fictionals if you cant find any more to join. I know one for sure that has all you mentioned except the "jabba t hutt" type of names.
Check out Home Town Baseball at <a href="http://www.baseballsim.com" target="_blank">www.baseballsim.com</a>
No openings now, but you never know.
Also, keep your eyes open for a NEW fictional on the horizon!!
