[H2k]

Hello every one


i have visit one website when i try to Regisiter it tell me

Only by inviteing

i go read the rulez how to Reigister .. then i see that

every user have in their UserCP options to send Email to the Person they need to invite him

for example

link http://www.thesite.com/forums/regisi...56465432356456

when they check on this link it will come the page where they can Reigister

dose any one have any idea about this hack ?

thankyou very much
