Damallsvenskan Talk

Bigsoccer is a huge, USA-based soccer/football discussion forum. It's big enough to accomodate a section for women's football. You can find both news and, if you're lucky, intelligent and entertaining discussions. There are usually threads about or related to Damallsvenskan in the
International and Rivalry subfora.

This British site has a forum with a surprisingly active women's section. Another surprise: there are a lot of Sweden fans there. You can usually find threads both about Damallsvenskan and the Swedish national team. Clubs here and Internationals here.

Women's Football Forum
Recently started forum with focus on the English scene, but also a vast international section. A European section with a subfora for Sweden and UEFA Women's Cup as well as a World section.
