We're happy to announce that you can now donate to PMMP using one of the methods linked here. For those who want ads removed on the forums, $3 or more per month via Patreon will allow you to have advertisements removed for your forums account. We're also looking into offering advertisement slots for services on pmmp.io in the future.
We don't have records for previous donations (that are not via patreon), but note that the no-ads benefit are per-month recurring donations via patreon.
Several of us have access to the funds, team members can spend as needed. Mostly this is expected to be server hosting and software licenses (like XF).
