[For the most part, these sites are selected by the staff of The Cauldron: A Pagan Forum or suggested by forum members. We used to have a form for the webmasters of Pagan sites to suggest their site and do link exchanges but it got to the point where we were getting 15-20 spam requests for every actual Pagan site (and the Pagan sites were getting lost in all that spam), so we reluctantly dropped this feature.]
The Pagan Federation
The Pagan Federation is a British-based organization of mainly European Pagans. Their web
site is an excellent introduction to Paganism in Europe, with links to other European sites.
The Pagan Pride Project
The Pagan Pride Project sponsors public Pagan Equinox rituals and charity drives every September, that is, they are the group behind Pagan Pride Day.
The Witches' Voice
The Witches' Voice an excellent "activist" site on the Web -- and in spite of the name,
it's not just for Witches and Wiccans.
