If you wanted, you could ask for a "middleman" in the announcements/queries sub forum. Asking for a long time forum member and or a Plat member. Maybe one of the mods has time, they may respond.
Or send the parcel insured and signed for/recorded delivery, and you will be able to prove it was delivered to him, and he should be able to send you tracking details for your parcel.
Or, ask people on here if anyone knows him. Never know, might get 20 replies saying he is a super sound bloke.
