	Every month, on the 8th and the 22nd, each TorrentMaster gets two invites (max of 8).

	Then, every month, on the 8th and the 22nd, we give out bonus invites like this:

	Every Power User, Elite User or TorrentMaster whose total invitee ratio is above 0.75 and total invitee upload is over 2 gigs gets one invite.
	Every Power User, Elite User or TorrentMaster whose total invitee ratio is above 2.0 and total invitee upload is over 10 gigs gets one invite.
	Every Power User, Elite User or TorrentMaster whose total invitee ratio is above 3.0 and total invitee upload is over 20 gigs gets one invite.


	This cascades, so if you qualify for the last bonus group, you also qualify for the first two and will receive three bonus invites.
	So a TorrentMaster who fits in the last bonus category gets 5 invites every month on the 8th and the 22nd, whereas a power user who fits in the first category gets two invites on the 8th and one on the 22nd. A power user whose invitees suck only gets one invite per month.
