A good Macross discussion site.

Here's a couple of other boards that I frequent:

 

http://www.macrossworld.com That's a great site with a lot of helpful folks. There's also a ton of information on Macross collectibles.

 

http://www.animenation.com is a pretty decent site for anime stuff, but you have to wade through a lot of crap in some of the forums.
