Well, what should we talk about? I'm twitching for some chatter but not sure what to talk about CAH wise. Though the first thing that comes to mind is the topic NMS and I talked about last night, mainly the difference between metahumans and mutants. Not sure how interested anyone would be in that though... Any takers?

I really don't think distinguish between these two terms.  Since both of these terms come from DC and Marvel comics (respectively), let's see how they use the terms.

[quote=Marvel Wikia - Mutants]Mutation is caused by the X-Gene in the mutants' DNA.[/quote]

[quote=Marvel Wikia - Metahumans]One of the Dominators discovered that some humans had a "biological variant" he called the meta-gene (also spelled "metagene"). This gene often lay dormant until a moment of extraordinary physiological stress activated it, and upon activation it would use the source of the biostress as a catalyst for "genetic change," resulting in metahuman abilities.[/quote]

So, basically, metahuman and mutant is basically the same term (some sort of gene gives the potential for powers).  However, DC wikia also mentions that other characters, like Superman, Wonder Woman, and Aquaman, have been called "Metahumans".

Therefore, I would say that "metahuman" should be a catch all for all people with super powers.  I also would not limit "mutant" with "abilities produced by genetics from birth".  Mutations, from what I recall from biology, can happen whenever in a animal (or a living organism's) life.
