Just a thought, but if a merchandise store was added it could help boost incoming revenue to some degree. One such possibility could be a store from Zazzle.com. The store owner has the option of designing the product/s to be sold. Beer steins, coffee mugs, sweatshirts, hoodies, dart boards, whatever. Throw the Roll20 logo on a few things, open a storefront and get some more advertising at the same time. Nothing ventured, right? This would make the T-Shirts available again, plus a plethora of other items, if you chose to include them. Not sure if it fits your business model, but thought it worth mentioning and getting community opinion.
