I run four vBulletin boards. One gets about a dozen posts a week, another maybe a hundred, a third perhaps a thousand (mostly people being silly), and the last about four thousand posts a week. The question for me is not size, but whether or not I get some value out of running them.

I have a small forum, 2000 members w/ about 250,000 posts. I totally agree that if it's under 10,000 then it's consider a small forum. But that's just me.

My site is just over a year old and has these stats;

Threads: 5,575, Posts: 112,896, Members: 1,604

I'd assume thats quite small in comparision to others.

Good ratio for members and posts though

Id Say 250,000 Is the Semi-Big Board Status

And the Site Turned 1 Yesterday

I would consider 1 to be very small
but 2 to be semi-small
whilst 3 relatively small
4 not so small
5 getting there (but still on a small scale).
6 to be (nearly there but your little bigger than small but smaller than medium sized)
7 smaller than medium size but bigger than small (but your still small)
8 Hey I'm still small but I'm a happy small
9 small-ish
10 to be gigantic (big-board status).

Congrats! For both of your sites just making a year those are very nice stats. I would love those numbers after 1 year. :)

Thanks !!
