I am a new member here, so I haven't the slightest how many usually are. However with past experiences of other forums, this particular type of forum (the "anythin goes" pretty much subject matter wise) usually gets the most visitors then any other forum type.
you can see this on market swag staticis on the forum home page. you can get all details of market swag like members, forums, new posts and new threads or topics.
hope this will be help
