The auction module works, now that 99% of glitches are found and fixed. We car get donations: tunics, swords, trinkets, to auction off. This can be general funds, or event funds. IT can work with regent to run.
EDIT:
Taxes are weird! Sales tax is based on where sale happens, might be a state tax only ship county to count in CA. Local tax is sold and picked up same country. This might be more than we want to deal with.
However, services are non taxable, so if someone wants to do a fundraiser auction for one on one swordfighting training, that's non-taxable and easy!
