Wow. How did they get that many post with only that many members? Probably short replies. I define largest as the number of visitors it receives at any given time. Digital point averages 2k visitors at any given time.
Actually, if you are just looking at Currently Active Users, that is just the users that have been active in the last Session Timeout period. Default is 900 seconds, or 15 minutes, but it can be set to anything. It is not a list of active users *right now*.
Digital Point Forum is one of the biggest forum but they are not user-friendly. Their moderators are very rude and that place is filled with spammers and scammers.
instead of listing them all because you know them, why not just go there: http://www.big-boards.com/ ...
does big-boards get updated anymore? There is another one at http://thebiggestboards.com as well that seems to get updated, just not as many features it seems.
