nah you need to signup first day of each month, ive just joined today so i dont have any invites. you need to be a power user or whatever if you know thebox.bz then its extremely similar to that site, theyre both full, but with thebox.bz you can keep trying to signup and usually you get through after a few tries, might be the same for PAT, its like when a user gets auto-deleted for bad ratio, a space becomes available.
