Has this been addressed by Talk Board in the past?

The topic was raised on the OzFest thread this week concerning future events. One member has suggested a $10 fee be charged to attend an event to cover administrative costs, with any leftover money from this fund donated to charity. Other members have countered that they have absorbed these costs in the past and not passed them on, and as volunteers would not consider an administrative fee.

I can't recall paying a user fee to attend FT events in the past, though would not be surprised if some prepaid dinners had a few dollars added in there to cover any extra costs.

Is there a policy regarding administrative fees to attend FT events? Does this fall within the purview of Talk Board or the purview of the Community forum moderator, or perhaps neither of those and is the sole decision of the event organizer?
