Forever Club: Can we offer more levels of Club Membership?

Can we please add at least two more levels of Club Membership to our offerings?  Currently, it is a big financial jump from $120 a month to $300 per month.  If we could add a $180 level that offers 3 Free gb per quarter and a $240 level that offers 4 free GB per quarter it would be so helpful.  And if we really want to create bigger opportunity...how about a $400 level (7gb free per qtr) and a $500 level (10gb free per qtr) to encourage our larger spenders??
