Read everything carefully to see if you want to open a collection.
fundable takes a cut of what is donated.
If you don't get all the $$ you're requesting by the deadline, you get none of the money. So, keep your request on the small side. But, if you get more money than you originally requested, you get to keep it.

If you do open a collection, make sure to post the link here so folks can donate if they have extra funds.
