hi Barbie...i'm only another user, but i'll chime in...you don't need to "go premium" to solve this...personally, i pay for the "remove ads" feature. i just popped $25 for 100,000 ad-free views & consider it well worth it. perhaps your members would be willing to kick in, or have a raffle maybe, & you can get a million ad-free pageloads for $125.
or, you have handpicked sponsors i notice...after you pay nabble to remove ads, you can always code in banners from your direct sponsors, then you'll know the place will remain clean & relavant for your users.
