Is rutracker invite only because I can't seem to find the sign up page. The register page is just the guide lines.
You want rutracker.org, not .net or .com. You also definitely want to use Google Chrome to auto-translate the Russian to English.
Edit: On the register page you must make sure to scroll all the way down to the bottom of the page where it says "I agree with these conditions".
