Comic MU*s

What's out there right now that actually has an active playerbase? Preferably canon Marvel or DC.

www.mutantgenesismux.com (x-men and brotherhood only)
unitedheroesmush.com (WARNING)

The WARNING on United Heroes needs to be reiterated a thousand times. It is not a good environment to play in.

Flashpoint: Gotham is also opening up soon.

I believe there's also CoMUX (http://cmbeta.wikidot.com/) but I'm not sure how active it is.

I believe that comic adventures is still going, too.

I also just found the site for Maelstrom Earth, but other than seeing it's up, I know nothing of the game. http://maelstrom-earth.wikidot.com/

Wolfs

CoMux NuGenesis, I think, is the name now, and it's had a boost in players since the UH fiasco.

Just tossing the wiki up for Flashpoint. Thanks to @Ganymede for mentioning it!
