PDC registration now open

I have a long list of backlogged things to post about...but for now, I just want to quickly note that registration is open!  We also posted 50+ session titles -- these aren't the final titles, but they give a pretty good flavor for the kinds of things we'll be covering.  You'll see some info about IE in there, and lots about Longhorn.  There will be even more details coming over the next two months as we finalize the session list and speakers.
