Is there any other way for me to make a ps3 account?

is there any other possible way for me to make a ps3 account? my ps3 doesnt let me make any more (the ps3 used to belong to my cousin) it just keeps saying that the maximum has been reached for this system or something like that and also the site is still down for maintenence or something so i cant use that either. so can someone plz tell me what to do now? thanks
