If i understood right in XBTIT DC there is no users promote system and no protected account for staff(all staff can see the other staff details) and from screenshots i don't see a torrent request option although Beyond HD if i record well had a system like this back in the days
if you have the mentioned above included in your XBTIT DC i will buy it on instant :)
I do play offline for few weeks with nexus and i know what can and what can't
I like the feel of your code but let me know if you can add those features mentioned above along with some mods to detect ratio/credit cheaters
