CardSpace and Community Server
In case you missed Ken's announcement, Dave's plug, or even Rob's shout-out, I figured I'd mention the Sacramento .NET User Group event occurring later today, Tuesday September 26th. If you live near the Sacramento area, be sure to make time (around 6pm) to learn about Windows CardSpace and how we've successfully integrated it into Community Server. I am looking forward to attending (and I'm also secretly hoping to chat with folks interested in CS)
Oh, and just in case you're still not sure if you should attend, remember Ken's got some cool t-shirts he'll be giving away... :)
