Linuxforums.org- Registration / Login Problems for AOL Users
Some people who try to register or login to linuxforums.org while connected to the internet with AOL make experience problems - becuase you are connecting to the Internet with AOL.
In their (AOL's) efforts to be as non conforming to Internet standards as possible, they route all (and cache(keep a copy) of most) your HTTP traffic through a massive collection of proxy servers with different IP addresses, meaning that everytime you make a request for a web page it can potentially be coming from a different IP address each time. This causes problems for software like phpBB (which we use at linuxforums.org) as it uses (among other things) IP addresses to keep user sessions active.
Short Version of all that: If you use AOL and cannot login to these forums - upgrade to a real ISP.
