Chris Shiflett has posted this new item today with a mention about the PHP Security Forum (a service of the forums of the PHP Developers Network).

I've already spotted a few topics that look interesting to me: Best Practices for "Remember Me"?, Question about session hijacking

I've been contributing to the SitePoint Forums lately. Although they don't have a forum dedicated specifically to PHP security, the topic comes up frequently on the PHP and PHP Application Design forums.

For those that haven't checked out the PHP Developer's Network forums before, you should go on over and check it out. There are tons of users on it daily, and the forum admins are doing a wonderful job keeping things running smoothly...
