Is drop trading supported by heRO?

[Ptah]

For that it's certain yes. If you have time. and even better SS of the trade and agree to trade.
Furthermore, drop trading is not supported at all, if you lose item dropping it, there's no way to get it back. Unless the guy that took it will turn out nice enough to give it back. (And yes, i know for sure, asked one of GMs on that matter, on the other hand, it happened AGES ago, yet i don't think anything changed)
