It's very exciting to see the different creations that people in the TFS community are creating using TeamSpec. At the outset of TeamSpec, we set to solve the stale document problem. In the process, we ended up created an environment in Word that enables documents to stay synchronized at the item level.
Check out Willy-Peter's (VSTS MVP) post about his initial experience with TeamSpec at http://dotnet.org.za/willy/archive/2008/02/21/teamspec-v1-0-what-a-pleasure-on-tfs2008.aspx.
Let us know how you're using TeamSpec. Post it on your blog or send us mail and we'll post it for you.
Oh, and by the way: We're very close to finishing Rich Text support for those work item fields that are stored as the HTML format on TFS. Rob Schlender (one of rock-star devs) is truly making magic in making Rich Text support a reality. I'll make sure to get a video together once we get closer.
