Definition of a "big board"?

I'm on the staff at a couple of different forums (check the first 2 links in my sig), and I was wondering if either one constitutes a "big board"?

The definition used by Quentin, who runs www.big-boards.com, is 500,000+ posts.

TheAdminZone.com uses the same definition as big-boards and host the forums for that site.

BigBoardAdmins.com has the definition of 100,000+ posts.

vB.org - no idea what the definition this site uses, but I suppose it's something similar.

I think vBulletin.com defines it as 1,000,000+ posts.

[Erwin]

There should be an official definition for use on these forums here.

[dbembibre]

I think that 1.000.000+ posts is a really good definition

all in favor?

There are currently 1001 "Big Boards" running vB on www.big-boards.com, which is the original Big Boards resource AFAIK. In my opinion, we should use their definition, 500,000+ posts. Why re-invent the wheel?

[Erwin]

Well, despite the fact that I pushed for this forum to be set up at vB.org, it's obviously not working at the moment as intended as there are a lack of rules around what should and should not be posted here. I guess I'll post a lot more at the Big-boards forum at TAZ, BBA and other places until that is sorted out.

I think it should be private for big board admins with 500,000 or more posts (because those boards are the ones who will need more specialist help with issues regarding large boards, and they'd much rather talk about such issues amongst themselves).

Look how much of a success the private sections are at Taz and BBA and they have no where near the userbase vBorg has...
