I've been a Community Manager for multiple communities throughout this last 6 years. Been using vBulletin, IP.Board, xenForo, SMF, MyBB and anything you can think about (Except Burning Board, don't like the theming part).
xenForo doesn't only generate a thread per resource created on the RSM, but that also allows the Config creator to both receive feedback and perhaps in the future sell their resources. Like some other guys have said in many other forums, it doesn't have to be only paid, you can offer free resources alongside the paid resources just fine. A very good example of this is xenForo's Resources Manager on their Customers Forum as it displays both Paid and Free Resources together.
Not only Resources wise it would be.. well.. wise, but you could also integrate it to your billing in order to have sync up with the forum account and mark those accounts as Customers. We all know the hard work that goes behind TCAdmin and we'd like to have a legit place to share our configs without having to deal with people that have decided to Null their way through TCAdmin's Monitors and all of that.
