Via the Scot Goes Pop polling fundraiser for 2021-22, which I set up in the autumn and is part-funded.
If you prefer to donate directly, that can be done via Paypal or bank transfer:
My Paypal email address is: firstname.lastname@example.org
Or email me for my bank details. (My contact email address is different from my Paypal address, and can be found in the sidebar of the desktop version of the site, or on my Twitter profile.)
