Reffing Experience/Preferences (Quaffle, Snitch, both): Quaffle, one "match" of snitch. I reffed two official matches, one or two NAPs and practiced with HQT.
Summer Availability: Gone from 21st to 31st July, though if it is told a few days beforehand, I might find a cafe or something, where they have internet access for a couple of hours. Otherwise free. As for hours, anything between 11 AM HOL and 10 PM HOL, optimal 5 PM to 9 PM HOL.
Thank you Dario!
