you have a good “Donate” page, but it is hard to know who to give to.
There is a nice (french) open-source platform for recurring micro-donations: Liberapay.com.
It allows you to create a team and the members of the team decide how they split the donations (one can also give directly to one person).
They eat there own food, since they don’t get money on the transactions (the fees are for the Mango costs), but also have a page to receive donations https://liberapay.com/Liberapay/.
I created a (small) pledge for the caddy team: https://liberapay.com/on/github/caddyserver/.
To receive it, you only have to signup and link your github account (to prove that you belong to the caddyserver team :-).
All the best and thanks again for this great software !
