This page is a part of the clean up project.
Social-Paradise was the first SANS website (Social Avatar Network Script) created by Isaac. Though, a website called jWist was created before he made SP. It was created in late 2011 and grew fast enough but slowly being more and more in-active.
MibZi is pretty much AvaWorld. It was shut down in the beginning of January due to spam, haters, DDoSers, and much more. MibZi merged with AvaWorld, and this AvaWorld was the result. MibZi had a store, a page of groups, a user-store, money, flash games, and much more.
Since then, MibZi has returned and can be visited at http://www.mibzi.net/Landing
