It was intended to be a completely open mailing list, meaning that anyone could join, provided they feel they might learn something form the group and were respectful of the user guidelines.
Posting frequency varied a fair amount, with sometimes a large amount of activity and at other times, nothing for days at a time.
The list was last Administrated by RazzaWolf, despite initial success activity on the mailing list dwindled as internet discussion forums became more prominent. Therians Campfire ceased operation sometime around 2004. For a time some archives remained and the related website "therianscampfire.org" remained up, however these resources are since defunct.
However, an archived version of "therianscampfire.org" can still be found on The Wayback Machine and more can be learned about the resource by reading the FAQ Section Linked Below.
