I'm crying right now. We've had SigmaChat Pro for months now and I knew nothing about this hack. Kudos to the author(s)!
Anyway, Raidersoft just started a new support forum and they're asking for a link to this hack, and others like it:
http://support.raidersoft.com/forums...4&hl=vbulletin
I'll leave it up to the hack author to respond. Obviously, they'll have to register a copy of vB to read these forums, so someone might want to upload the hack to RaiderSoft's servers.
