Religion Forum threads labeled Caucus
Caucus threads are closed to any poster who is not currently and actively a member of the caucus group.
For instance, if it says Catholic Caucus and you are not currently, actively Catholic, then do not post to the thread.
However, if the poster of the caucus invites you, I will not boot you from the thread.
The caucus article and posts must not compare beliefs or speak in behalf of a belief outside the caucus.
There is little to no tolerance for non-members of a caucus coming onto the caucus thread to challenge whether or not it should be a caucus. Gross disruption usually follows.
If you question whether the article is appropriate for a caucus designation, send me a Freepmail. I’ll get to it as soon as I can.
