Over at the Outhouse, a forum I tend to teleport to, Bubbakanoosh started a thread where you post your top 10 X-characters and he'll tally them up to make a list of from least popular to most. Whether its members from X-men, X-Factor, New Mutants, Excaliber or whatever. Any incarnation is allowed.
Here's the thread here. Also, post your top 10 and I'll just send the list over to him. This should be fun. I'm anxious to see how this goes.
