Steal one from the Terminix bug people

<Kills Reds Dead>

I made a guild charter for <Has A Posse> but haven't turned it in yet.
Can you use alphanumerics in a guild name, are they allowed? If so could you do something like : <They Went That Way ===>
I know I've seen people with | and a few others, not sure if it's against the naming rules or not.
