one more idea today..
I play Travian long time and almost in every ally at start we do push... (help slowers expand, rebuild aftere catas, make catas due to hostile neighbour, etc.).
We always do that with our merchants and reply to leaders, fill tabs, forums, google docs, etc.
Am getting older.. would be nice to have such menu in alliance just like Bonuses are. You would contribute resources and leaders would decide (function) who and how much can download and also others can see where it goes.. Leaders could easily see flow and how much who sent... and who did not or ho receive and beign farmed, etc.
I think it would be cool add.
