since this isn't *my* board, there really isn't much i can do unless the owners give me permission.
As RSNers will attest, i'm not real big on crap topics, but as they also can attest, i haven't locked a thread in ages, nor do i complain about the lack of substance in the threads. i never have to deal with flaming and other negative stuff like that. the posters on RSN are having a lot of fun, even if it seems asinine at times. I've come to the realization that that is what is most important. They are at least doing it within the sub-forum that allows for any and all topics.
i've found that in administering a message board, less is more. it pays to take a "wind it up and let it go" approach to moderating.
