btiteam.org is an open source support and development forum for xbtit v2. it is free
xbtit.com is the shopfront for xbtit v2 presenting the xbtit live demo, xbtit PREMIUM, xbtit PRO, and the xbtit private members forum
buying xbtit PREMIUM/PRO, or JOINING xbtit, gives you 10 tickets and access to the xbtit private members forum where you can swap tickets for btiteam hacks, modifications, and styles. members of xbtit can also request PRIVATE hacks, mods, and styles. membership of private.xbtit.com lasts for 1 year after which you will renew your membership
eventually, the hacks and styles on xbtit.com will be released into the open source community on btiteam.org
the difference between btiteam.org and xbtit.com is the same difference as between Fedora and REDHAT. xbtit at biteam.org is like Fedora, it is exciting and it is free. xbtit at xbtit.com is like REDHAT, it is supported and you have privileged access to private code
xbtit.com funds the free open source support and development at btiteam.org
