I must say, that I have encountered that in a couple of covens I've been in in the past.
I must say though, that my coven is very active. We are constantly posting and learning and teaching one another.
We are all of different paths but have the uptmost respect for all our members and their paths.
We all talk a lot to each other in coven chat and are very close, considering we are all in different parts of the world and meet online.
We have rituals we do together. I have even celebrated two of our coven sister's birthdays , while being in on the other side of the atlantic.
I feel that theres not really point in being in a coven that is inactive, you may as well not be in one full stop.
