List your item as usual on YOUR OWN account. Tag it "Artist Aid" or "Japan" "Tsunami Relief..." whichever you are comfortable with. Come back here & share your link. The collective group will promote via Twitter, Blogs, Facebook, etc. Build treasuries, etc.
**We do NOT sell your items for you. This is your responsibility. We're only a means of getting the word out. A larger voice instead of shouting alone. This gives you control over your money & the charity YOU support.**
Please remember to follow Etsy's rules on Charity. That can be found here:

Thanks so much for your efforts.
