Would appreciate input on adoption-related giving circle

Hi all, I've been thinking about starting a giving circle for awhile now (where a group of people pool their charitable contributions and decide together what to fund to make a larger financial impact). I would love to start a group focused on adoption-related needs. There are already a lot of grants/groups out there that help potential APs with adoption expenses, but that's not really what I'd be interested in funding. Was thinking more along the lines of helping anyone in the adoption world (adoptees, birth parents, adoptive parents, expectant parents considering adoption, etc.). I worked for a nonprofit for a few years (writing grant proposals/reports, managing foundation relationships), so I have some familiarity. There are a lot of different options for housing the funds/dispersing the grants, so that would take some figuring out. But I was basically thinking I'd get a group of 10-20 people together (each donating around $100 or so), put out a call for proposals (just asking for a short letter), then after reviewing, decide as a group through voting where to allocate the funds. We could ask for a brief letter report from the recipient about the impact. I guess with making grants to an individual we would either want to put the grant money directly toward the intended need, or ask for receipts after the fact, just to insure against fraud. If I really get started on this, I know there's a ton of research to do (how to get the word out, how to conduct the review process, establishing guidelines to make quantity of requests manageable, tax documentation for donors, etc.). Anyway, I was thinking it could fund basically anything that's adoption-related (i.e. helping an adoptee travel across the US to meet birth family, helping a birthmother with tuition to start school, helping an expectant mother considering adoption with specific one-time needs that could allow her to parent her child, and yes, helping potential APs with adoption expenses in unique, compelling circumstances beyond the garden-variety "we need money"). I don't know. What do you think? Could this work? What issues to you foresee? What parameters do you think need to be in place? Do you think this is manageable on an all-volunteer basis? Do you know of a group like this that already exists? Is this something you might participate in? etc. etc. Basically, I would just love some feedback from my favorite group of experts! Thanks! Jill
