I do not know, hence the "If possible", but I know for sure that it's possible to make a trad where OP is moderating it. Not quite the same, but you could remove any clutterposts.
I looked into it but it seems you cannot start a tread in the Auctions with OP as the mod.
Does anyone know how to get hold of a mod round here? I would like to see if they would be willing to help in the matter, but I can't seem to find one.
