	Power Users have a cap of 2 invites. Elites have a cap of 4.
	Every month, on the 8th and the 22nd, each PU/Elite user gets one invite up to their max.

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

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

	The bonus invites cannot put a user over their cap.
