For a while, people were having problems logging into the site. This was a cookie issue that has been solved.

PLEASE CLEAR YOUR COOKIES (or just delete the forum ones)
If you are unsure how to do this, this will help: http://www.aboutcookies.org/Default.aspx?page=2

Unfortunately, in order to solve this problem there will probably be issues with alternate forum URLs. These URLs are not supported. If you can't load the forum from where you are as a result, I am sorry, but the official forum URL (sr20forum.com) is the only one I can support. You will have to circumvent your work filter some other way.

Please post any problems you encounter with logging in or cookies here. Again, I'm sorry if those of you using URLs like "sr20performance.com" or "nissantuners.com" to get here are unable to do so any more. I am aware that people browse this site from all sorts of locations. If I can reopen full access with alternate URLs in the future, I will do so, but the functioning of the official URL is the most important thing.

hm. I seem to be having a problem, getting a notice that I must move the page to the "whitelist"? I have to clear my cookies everytime I want to login.
