There were two tournaments that were organised by RHP members prior to the official site-controlled ones you see on the tournament page. The first involved the US vs. the Rest Of the World (US vs. ROW), and the second was the Baker Invitational Tournament. (B.I.T).
The BIT is still in progress and is being directed my VAKNSO and LIONESS. In one of the BIT threads here, you will find a link to another site that has a graphic display of the BIT progress.
hope that helps,
