Boards:
http://www.ChristianForums.com I'm "Susan" there. Don't bother reading posts I made until about May or June 2002 because I was posting some of the silliest things (that was when I wanted to be a "good" hyperfundamentalist, lol, seriously, I posted some pretty messed-up stuff and I even tried to be anti-anime for a short while, until I saw that you COULD be Christian and a fan)
That's a really cool board. I really like it. If you go, please check out the RPGs and anime club. You're automatically a member if you're a fan LOL.
http://www.otakuboards.com This is a secular anime board, but one of the better such boards. Be warned that there are a few *discussions* of topics such as homosexuality/yaoi (and a few really mindless fangirls that think any male character in anime is necessarily not straight).
However, the moderation is some of the best I've seen on an anime board, and images/seriously graphic discussions are removed quickly. I really love this board, and I post, often in the Anime Lounge forum, as "MillieFan." By the way, if you go there, please drop by the thread "Legato?" in the Anime Lounge. We're discussing the nature of truth and why evil is evil there. . .
http://www.animeangels.net/forum2/index.php This is another Christian anime board. I like it, but it's really slow sometimes since half of the membership is inactive.
