Very nice walkthrough video about Community Server (of Telligent – presented by its president, Rob Howard, formerly an MS employee for several years)
It’s a very cool collaboration/portal server, with friendly WYSIWYG (what you see is what you get) tools for admins and users, using ASP.net. Personal edition is free. Here are some links about it:
Also at http://www.communityserver.com/ they have hosted version, where you host a community server at their own machines
An interesting blog on CS is at http://gcapnias.spaces.live.com/ (by a CS and MS MVP)
Have been looking for long time now for a good bookmark sync (between browsers and machines) and publish (+remote collaboration on editing/adding bookmarks) service. I think I have found it at Zinkmo! and started synchronizing my favorites and sharing them online with it.
Very nice service, has an online editor but also sync local add-on for IE and for Mozilla. Via the online editor you can select which bookmark subfolders to make public (and from the local app can also select which are private). Can also have some be accessible via invitation and define contributors for them (other people allowed to edit the bookmarks)
So, here are my public bookmarks (more to be made public in the near future):
