Many of us who own forums also post on admin forums. So in a way, we are advertising our forums to other forum owners. In the past, some of my best forum members were other forum owners who found my site and started posting there. These people were not just there for a signature line, but really got involved in my forum. Is this something you are finding to be true on your own forum, how forum owners make good forum members? Or, do you think they are only there for advertising purposes such as to get a signature link?
I think it really just depends on the person, they could be good or bad.
I've had some really good ones who write well and appear to care about what they're posting and then I've had the bad ones that are only there posting to benefit themselves.
I haven't had that experience. I found that people sign up just to add a signature link in complete disregard to the signature rules on my forum. (For now, I don't allow sig links to other forums because that can really hurt a new forum's growth. I'll probably change it when it becomes more established.)
They can, although, if they are only posting with the ulterior motive of you posting on theirs, like with a post-exchange, chances are that they will not be.
It completely depends on how happy/content they are with their own community site, and also on why they have decided to join yours.
Generally I would say that every added user is one more.
If there is fall-out, then this will have to be dealt with when it comes along.
With large user bases, owners are going to experience plenty of challenges. Why not from a few forum owners?
