The eclectic feminist pagan tradition started by Starhawk, author of The Spiral Dance, who pretty much defined eclectic Wicca in the late '70s. But she, and the group, seem to have moved on to more of a sort of generic pagan/new age/women's spirituality style of practice that doesn't really have a lot in common with Wicca in the traditional sense any more. Still interesting, though.
A nice magazine on women's spirituality, with widely varying content. A lot more down-to-earth than many of this type, and nicely designed (both the zine and the site). The web site mostly exists to promote the print magazine, but they do have a fair number of past articles online in the Sample Issues section.
The Sacred Feminine
Goddess art and poetry. The text is a little on the white-lighty side, but the artwork, by an artist named Montserrat, is absolutely stunning. Includes the most incredible background images I've ever seen, though unfortunately most of them are real bandwidth-eaters. Still, they're gorgeous enough to be worth the wait.

Information on cross-cultural women's spirituality, from female-oriented currents within Judaism, Islam and Christianity, to earth religions and more...
Yoni: Gateway to the Feminine
A really excellent feminist webzine from Australia, dealing with women's spirituality, sexuality, politics, and all the intersections between them. Highly recommended!
