Great idea ! But, I have something that I would like to see implemented at the same time :
My suggestion is : allow a guild to set a limit for each resource, for example 2000 gold, 1000 iron, 1000 stone & 1500 wood per member per day, to be auto-approved. That should make things go even more smooth and quicker. It would also relieve leaders from a lot of small errands.
If desired, it can also be made more individual, by setting the max. number of resources per individual member, so each member could have a different limit.
