It would be extremely help for all in a co-op if when a member request help that in the chat request it would show an icon with what it is that they are requesting and maybe a quantity but i would be happy with an icon.
I spend a lot of time bouncing in and out of others towns to determine what I can help with only to find that after visiting a few I forget what it is they are asking for. This proves to be more often true when checking my market place to see if I can buy what they need.
