What does the_fund do? In short, fanfic writers, betas and artists are offering up their services, for a price. The rules can be found on the community info page, as well as the basic prices.
I had already made all the monetary donation that I can afford right now to the Red Cross before I'd heard about this community, so I am offering my services to be purchased.
You can check out my offerings H E R E.
While I do not know the affected people personally, my heart goes out to them nonetheless. Homes and jobs have been lost due to Katrina, and they will need all of the help they can get in order to meet even the most basic of needs.
