FYI...
Used Sinisterpain's iCash enabled files for vBookie... seems to be working perfectly.
Kudos to Sinisterpain for posting the files. Unlike a few of the hack forums, there's a strong positive spirit of support and cooperation here.
With the other cash, banking and shop hacks seeming to be dead, Blaine and others have really stepped up in support of the vB user community. This hack should be a shoe-in for motm.
Many thanks to Blaine and everyone who helps out!
