For me, I am a paying member of the Scottish Pagan Federation which is affiliated with the Pagan Federation in the UK. I receive quarterly magazines in the form of Pagan Dawn and Espin and get lots of interesting articles, ideas and such.
Wondered if there were more around the world?
I used to be a Pagan Fed member back in the '90s - and was a visiting prison chaplain for them for a few years as it happens. I am also a member of the Fellowship of Isis but only small local groups otherwise.
