In previous events where all the travel was within Europe, the treasury committee has given sums of about EUR 150 per participant, plus about EUR 100 for promotional materials.
This request for EUR 462.80 is well in line with this rough rule of thumb, given the large number of 0 A.D. delegates at FOSDEM this year, which stands at five.
I also think our fiscal situation allows for this "ad hoc" expense. We have about USD 28,000, with about USD 1,000 spent every year on hosting. (In terms of Euros, those sums are equivalent to about EUR 23,000 and about EUR 800 respectively.) Until we do build a budget, I think we should reimburse the attendees.
Therefore, I vote in favor of this proposal.
