I need WWW forum. It can be based on phpBB or something else. It must allow me to put banners/own code between sites/topics and it must be security safety. It need to have good administration panel and very easy to manage ( adding new moderators, changing layout etc.). It will be used for about 500 person online and will stand on freebsd with apache, php and mysql. Also i need to know how to backup it and restore!
