I'll cut right to the chase - I'm looking to create some sort of semi-auto trading of items. I've started a team with two mages and I basically want to speed up the process of handing out water.

I know you can /trade, so thats the first step.

Now, as for Selecting an item to throw into the trade window is beyond me. If you could get past this step, the rest is easy.

Once the item is there, just use the accept trade macro.

The only thing you would have to specify is which character to start this "transaction" with.
