They have a website and a blog. And articles of faith:
The Articles of the Beaker Faith
1. Anything that can be reasonably conjectured when it comes to the original Beaker Folk, and not disproved, can be assumed to be true and therefore a genuine Beaker tradition.
2. Anything we don’t understand about previous generations was probably concerned with fertility rituals. Any object we don’t understand had symbolic meaning. Even if it could just have been a ritual back-scratcher.
3. The more inclusive you are, the less you have to worry.
4. There’s no spiritual power in the universe greater than wishful thinking.
5. All contributions to the Community are strictly optional. But don’t think that means you can get away without paying them.
6. Don’t jump and down on Thin Places in steel toe-capped boots. They’re liable to break.
7. Tea lights are nice.
8. Don’t ask the Archdruid about what she puts in her pipe, or why she needs such regular deliveries of hydroponic supplies. Or why the snow never settles on the roof of the Great House.
9. If it feels good, it’s probably fine.
10. Hi-viz is good for your physical safety and your eternal soul. We don’t just wear it because the Archdruid bought a job-lot of personal protective equipment in her old job as a Health and Safety advisor.
11. Whenever referring to "Celtic" Christianity or the "Celtic" tradition, we will always put the word "Celtic" in inverted commas, to indicate that it is no such thing. We’re still considering putting the word "tradition" in inverted commas also.
12. Never attempt astral projection without a safety belt and hard hat.
13. Avoid ever trying to understand what Beaker People mean by "the divine". Once we start to try and understand "the divine" it might in return make some demands on us. Keep your tea lights alight and your theology vague.
14. All religions contain at least grains of truth. But some religions are more profitable than others.
