Yeah. Shlee is a bit of an expert on fundraising for community projects. He has taken on the funding and maintenance of a few smaller mastodon servers after their original admins were no longer able; and he is the chief fundraising guy for pixelfed, the fediverse alternative to instagram. I'm on aus.social, and I've donated to the Posters Union a couple of times. (Although I think it might be renaming to Posters Guild, due to some minor legal pushback when registering it as an official charity or something.) And as you (Gorgritch) point out, he is a real-life person who also does various charity fundraising in the physical world amongst real people outside of the internet.

So yeah, probably it would be worth contacting him for ideas and suggestions.
