Grou.ps allows users to create online "social groups," adding the features that best meet your community's needs.

Share photos, videos and bookmarks; create a group calendar; collaborate via a wiki; aggregate content via a group blog; communicate by posting to the community forum.

Despite being free, there's no branding and no ads. And there are more than 20 templates to choose from, all modifiable — only integrate the features your group needs.

Check it out and let me know if it works well for you.
