Hi,
In short : when you alliance chat "Send Me Ressources Someone Please" and that you actually receive 3 or 4 full batch of caravans ressources each saturating your Storehouse / Warehouse, you could, by this way, be sure to limit the waste. Just click the one(s) you keep, the others would simply reset and send a message to the sender that the offer has be denied, and ressources laid back home. Maybe put a time limit to refuse them (say 3 minute for example) before automatically confirming it. Talking of confirmation, it would all be automatically confirmed by defaults, when not dealt with by receivers.
Of course, when offline, everything would be always confirmed... But that would still be useful, as, I think, most of the sent caravans to allies are send when asked on the alliance chat by member of said guild.
Having the amount and sent delay of all caravans, the choce would be easy, and would even correct said errors (like, in my case, when I receive 30 000 clay instead of 3000...)
I think that would be simple and useful for everyones.
Thanks
