How do I use coins?

Hi guys,

I donated $10 in order to skip the queue for Outland. and now I have 10 coins. What can I use them for?

Also, what are points for?

Points are a free currency that you can get from having achievement points on the other expansions. This doesn't currently apply to Outland.
Coins are used for a variety of services, like faction changes, character recustomizations, and other things that we offer like purchasing available gear on the marketplace. Currently, at this time, I do not believe that there are any available services that require coins for Outland. I could be wrong due to having missed something, but for now, just hang onto the coins until you need them for something.

OK, I see.

I browsed around on the Account tab. It looked like it might be intended for buying and selling of items and gold. There is no way to translate coins (or money) to gold? I seem to be short on gold since leveling is so quick.

There is IF some1 posts gold but due to shortage on all fields i doubt ul see it that fast.
