To be perfectly straightforward, we're currently debating this thread in the mod forum, and how it fits into our solicitation policy. We technically forbid "solicitation" for charities, but whether goods/services fit into that definition isn't adequately defined. Also, how a work of art is defined as a good or a service (including the intellectual property rights to that art) is not something we've yet hammered out.
In addition, we might be implementing a new solution for organized listing of events.
Either way, the policy decision will likely come into place after this thread has passed, so you guys haven't done anything wrong, and you're good to go for now.
