Some guys tell me they are having trouble getting logged in, they say they try to log in and the process takes them back to the main page, still not logged in. Try clearing your cookies and temp internet files and be sure to try using Internet Explorer 6.
To assist, I have run a script that should reset the subsim forums cookies that allows us to stay logged in. If you have any trouble getting/staying logged in, go to your browser's
Tools, Internet Options, Delete Cookies.
