So, you have an event you'd like our GMs to come to. We do have some restrictions, as we are a volunteer non-profit group.
First, we do not generally do for-profit events. We are here to promote the benefits of social tabletop gaming, not make money for a company.
Second, we're not babysitters. If there are kids present or participating, we will need a responsible adult (parent, guardian, teacher, scout leader, etc.) to be present for the entire duration of the event.
Last, we are not a replacement for the forever GM in your private gaming group. Sorry.
