Perhaps you could reverse the solution I gave and allow a subscription for people to get additional features and no ads if they subscribe. Let's say if the hosting here permits unlimited email accounts. Maybe if people subscribe and pay so much, they get a free email account, no ads, and other benefits.

Yep, perhaps further down the line some sort of "premium" account could be implemented. This would include no adverts, additional features and the like for a small payment. I have no intention of turning this into dnforum.com though haha! Adverts or premium accounts are the only means of taking this community forward and for now...there will be adverts.
