I wonder if you know any forum that has a big number of members at least 100,000 members like:

http://www.vbulletin.com/forum/ 150,000 members

Maybe WHT. But it is difficul to say how many members do they have.

True True. WHD has a site directory in place. WHT picks up off where WHD lacks. Forum members

You may go to Webhostingtalk.com or Webdesign.net, Hostbidder.com.

Its difficult to count the members of any good forum. Some prefer the niche area forums..some like the general ones...!

icq form is the biggest

thanks for info.
