The deadline for registering for the Tsunami Beach series came with less than 30 registrants… so, per SLSA Competition Event Rules
1.3. If more than 30 legitimate registrations have been received by midnight Second Life Time (SLT) on the Tuesday preceding the date scheduled for the Open event, registration will be closed and the Open event will proceed. If 30 or less than 30 legitimate registrations have been received by that time, the Open event will be merged with the Pro event and registration will remain open until midnight SLT on the Tuesday preceding the date scheduled for the Pro event or when 30 legitimate registrations have been received, whichever comes first.
Basically registration was 30 or less for this event, so the Open is merged with the Pro and will be held on the Pro event date. Registration will stay open on the Forums until next Tuesday, the 9th, or 30 people register, which ever comes first.
