On Big-boards.com I noticed it is showing exact same no. of posts and same no. of members as DP currently have. When DP forum was submitted there it must had less posts and members but now it is showing the current no. of posts and members. Does anyone know what kind of script they are using to get the latest stats from submitted forums?
Does vbulletin provide this data in an RSS feed?. If not they may use php functions like get file contents. Then they'll parse the homepage HTML for the statistics box.
