My first anime club wasn't really an anime club, it was more of a gaming club (and by gaming, I mean halo. And I suppose I should mention it was in High School). So we'd have maybe 30 guys acting like douches while playing halo...and maybe 10 people (including a few girls) watching anime in another room. One of my friends ended up taking over after I graduated and the club grew.
I've been involved in my college's anime club since I was a freshman. It was only about 10-12 people (myself included) when I first started to go, but it grew over the years to somewhere between 40-50 regulars (with a respectable number of girls, though there are still more guys). There are a few creepers, but I'd say most of the people are rather normal. Attendance for the past 2 years has dropped, which I attribute to two things. One reason is the format change (went from watching complete series with members bringing in a few episodes of a random series each meeting to theme nights), the other is the convention that has taken up nearly all the money the club gets (save for member fees) for the past 4 years.
Other than that, my college's club has had a few other distinctions:
-One of the most well attended student orgs
-One of the (if not the) most diverse student org
-We sued part of the student government, and won
yeah, the UW-Milwaukee student government has
pretty much been corrupt since I started going there. We sued the student allocations committee after they denied funding for Anime Milwaukee due to rules they made up on the spot (and they don't allow submission of anything during the allocations hearing...so they pretty much ruled us out before we even showed up). Also, that reminds me of the year the SAC lost our paperwork (which had to be done in octuplet...or nonuplent if we wanted to keep a copy) which forced us to be the very last hearing (meaning they're way past the point of having given out all the money they're going to give)
tl;dr
my college animu club is a pretty cool guy, eh has girlz and doesn't afraid of student government
