I was wondering, what if a donations site, retrieved, with your permission, your Facebook groups, then asked you which ones to include, stored, them, securely, with your profile, on their site, and everyone on the groups you included received a request to contribute donations, and, you could then see, who donated, and, at your option, how much (ad horizontal histograms next to profile pictures and names), and, below, from the server offered by the donating company, you could even read the comments, of, the donors (who may also have chats, e.g., by telephone, with the entity they are donating to, and, after, the calls... post in the comments below.
Everyone sees the comments by the people in their group they donated with.
Optionally, they may also see global comments.
