couple of things:
I read through here but didn't see it mentioned - is there any easy way for others to make one time donations? ie, do you have a paypal account or similar that I could send like $100 or so? not a ton, but might add up if others chip in as well.
also, I thought of something that might be worth looking into for your charity. not sure if you've heard about or used it, but "amazon smile" lets charities register on there and customers can shop at smile.amazon.com and amazon will donate a small percentage (I think it's 0.5%) of the purchase to the charity. I figured if your charity is eligible (I don't know details on how that works but I think it just has to be a 503c??) and you registered it, people here that use amazon could support your charity by making purchases they'd make anyway
I found this which shows the listed charities:
AmazonSmile Charity Lists
something that might be worth looking into if you haven't already. and if you have, please let us know so we can support it that way
edit: think this is the info on registering charities -
AmazonSmile Org Central: Customers shop. Amazon gives.
