The best way to donate is to support ARtemisia’s Patreon Page. For as little as $1/month, or as much as you like.
I have many projects going on at once–books, plays, lectures, music, skypes, the IAS and more. Every little bit helps. Patreon makes it easy and cheap to make a difference. You can also consider becoming a sponsor, with business benefits to you, if you are in an appropriate/related field.
