CoRank is a site which lets you create your own social bookmarking sites, which are hosted at – a similar kind of thing to what Ning does with social networks.

This is a great way for small groups to share information through weblinks between each other, without going to the trouble and expense of setting up something like Pligg on a server.

I’ve set up a CoRank at – feel free to join it and have a play. I’ll still be using as my main bookmark repository though.
