It depends on what you want as a forum.

Do you simply want to survive with the same, relatively small group of old friends, and see other posters come and go, or do you want your forum to grow and attract more intelligent, knowledgeable posters from all kind of circles instead of pushing them away?

Neither of them is wrong, but there is a big difference.

Don't get me wrong, this board is a great source for mob history, especially if you learn to use the search engine.
