If you registered for the February 21 Scott Andersen meeting (just the first session, at 7:30 AM PST), you should have received an e-mail saying that the meeting has been rescheduled for one week later, on February 28. Sorry for the inconvenience... but we decided it would be better to wait one week and have a presenter then to hold it as planned and sit there in silence for an hour.
The registration link on the MCP homepage is going to the updated event page--that text will be updated within a day so it says the right thing. If you registered before, you do NOT need to register again--just update your calendar for the 28th instead of the 21st.
The SECOND session (5:00 PM on February 21) has not changed. Registration info on MCP homepage, too.
