This looks pretty interesting. Got a couple questions, if you don't mind;

What kind of 'powers' are the supers allowed to have? Is it based on technology, like iron man, or more like X-men where some people have one specific 'power' they can do things with? I'm assuming people at superman level are off limits.

Who's already in the group? A general, simple explanation is all I'm after. Names aren't even required, I just want to know what character concepts are already in use without needing to read the entire thread.
