Muttle provides cobranded freehosting for free with a 50% ad share. Many of the members wanted a free main site without ads, and I've taken their suggestion.

What you get:
-100MB of space
-Unmetered transfer (this is for hosting sites that will be promoting your freehost, not download sites or anything, so bandwith is not a problem).
-No Ads
-50% ad share on member sites.
-Control panel to manage members.

What you need:

-You need to have a site that actively promotes your muttle cobrand.
-Your community must be active and have traffic.
-Your site must look nice.

If you are interested feel free to post, pm, or email me.
