I found this site quite interesting but this site is "invitation only",no referrals just plain invitation from a current registered user. So i have a premiun account in lockerz having free 300 invitations.
So i am giving away 250 free invitation to my fellow users on hubpages rest are for my friends and family.
Do join fast or you will miss the chance of joining for free.
I am posting this blog on 17th october so try your luck at getting the invitation as soon as possible.
I wiil send u the invitation as soon as anyone sends me his email id on my email id
Have fun guys.Enjoy the moment
