Foundation style sponsorships are key to community news networks:

• Shared commitment
• Allows benevolent giving by those who will gain or want to give back
• New community members come with an interest, looking for a place to freely share
• Eventually, new members may find they have much to contribute back
• Banners are a simple way to acknowledge those who provide financial support to power the infrastructure for the community.

One or many news sections, blogs, forums, whatever makes sense for the community.
