Hi. You need mod approval to run such an auction, and a finish date/time, and info regarding P&P (eg is it included in the final bid price, or is it on top/extra, and if included, what type of post service will it be?), too.
I have run many H4Hs auctions on the BBS to date, so any Qs you have, do give me a shout. Meanwhile consider your idea/auction mod approved (by me ), and I have moved this to the fund raising section accordingly. Finally, let me get the ball rolling with an opening bid of a tenner. Atb: G.
