Calm down everyone... The waambulances are on their way.
1) Help a noob... - Have said noob post a trade for one of their fish for whatever resource you want to give them.

2) Gem items... - Post a trade for one of your fish for the agreed payment. Once trade is accepted, gift the item.

3) Buffs... - Have the buff seller post a trade for one of their fishes for the buyers gold before/during/after buffing.

4) Auctions... - For the most part, auctions will probably be limited in what is useful to run, but can obviously still happen. Auctions
for bulk items will probably lose their usefulness, but that's probably for the best anyway. It's one of the reasons that many items
aren't profitable to make on your island with artificially low prices carrying over into the marketplace form the auctions. It will still be
an awesome place to do business for things like resource depos and gem items.
Simple solutions are easy to see when your eyes aren't filled with tears.
Oh! I think I can hear the waambulances coming down the street now...

Have a fun ride.
P.S. If you decide to rage quit over this, I can 'store' plenty of your goodies, as can my fellow chillers. Just let us know...
Edit:
5) Loot Spots... - Post a trade for one of your fish for the agreed payment. Invite the guest to your adventure.
