All forums ebb and flow.
I belong to quite a few machine forums, some very active and some not so much.
Here and again, I do moderate a new member post or two on this forum.
I have a bit of experience with forum management due to the fact that I'm the administrator of a support forum with about 17,000 members, some very active and some never.posting a thing, but merely lurking, Some months we have a lot of traffic, while in others we drop off..
For example, in August, we had over 9300 messages, while just last month we had about 5400.
Just the nature of the beast I suppose.
We get a ton of spam hits and even a few that slip past our filter, but all in all, I make sure our staff runs a very tidy ship.
I'm at the point now that I can almost smell a spammer.
I'm coming up on my 5th years as our admin, so I'd like to think I have a handle on it by now ;)
