Please see the USAL log for current information.
Playing on the USAL judge requires complete and accurate registrations. At a minimum, you must include your first and last names, your site (obsolete, but still required), your address (city and state at a minimum), your telephone number (use xxxx for the last few digits if you wish), your email address, your country, and your level (one of novice, intermediate, or expert). The web form is probably the easiest way to do this.
I had to start using a blocking list to cut down on the amount of spam reaching the judge. If your email to the judge is getting blocked, here are the directions to get unblocked.
Email in excess of 15000 bytes is also blocked. This should not be a problem for normal plain text email to the judge. The two most common reasons for exceeding 15000 bytes is sending HTML mail, and including long responses (like help files and histories) at the end of messages.
