forum statistics scraper

Hello, i have a list of URLs to hundreds of forums and now i need to know, how much members, how much topics and how much posts each forum have (this info is on the homepage of each forum in the footer). That is a lot of work to do manually, so i need a script or a program that can copy/crawl/scrape these statistics for me. It should work with following forum softwares: - vbulletin - woltlab - phpbb when possible also with: - xenforo - IPB - MyBB - SMF If you have questions, feel free to contact me. Regards, Zakadu
