I used to enjoy going to Pokemon forums, which were the first type of forums I ever went to and joined. However, I eventually stopped for the most part, keeping to debate threads and trying to post the odd fanfiction. I really do despise unoriginal Pokefics, LOL. I can't stand thinking about how often a story would come up that was either the author living out the games or a "borders on porn" shipping fic. I have my "I want to live with those characters" moments, too, but here I try to keep them to Dorm fics.
I did participate in the forums on fanfiction.net in the Labyrinth section, but quit after I was accused of being a rude person who didn't even deserve to be a fan all because I pointed out that it isn't canon that Sarah loved Jareth, considering the plot has her break free of him at the end. I was flamebroiled to a crisp over that one.
I don't run into too much drama here. There's the occasional spat. I also concede that sometimes I take things too personally, particularly one week out of four, LOL. There seems to be more of "outlines" and such here than in other places, where that sort of thing is considered no-no, or is given a sub-forum such as "outlines and story ideas". I can't decide if the Pokemon forums I used to attend or this site has fewer people who get offended by honest criticisms and offers of assistance. Back when there was a site called Pokeschool, I loved this one teenage boy's reviews: they were always so in-depth and demanding and professional-like. I credit him with the improvements I've made over the years writing fics. I'm probably too lazy a reviewer, but it seems like fanfiction can be just as "sacred" as the franchises on which they're based. I mean, I spent a lot of energy doing Comeback King, but if someone wanted to offer criticism (not griping, mind you, but honest mature criticism), I'd be more than happy to accept it, because a story should be justifiable or it should be fixed so it is.
