Congrats dude!
Find clickbank products in your particular niche that you can push at your members, may help bring in some extra revenue. CPA offers may also be a good money earner.
I definitely wouldn't move away from this membership site, until you've milked it for every penny you can squeeze out of it.
Getting itchy feet and wanting to jump on to the next big idea, is a mistake many noobs make.
Get this site earning over $2000 consistently each day, then either hire someone to run it for you or sell it on for big bucks!
Good Luck!
