If not, NOW is a great time to sign up (and be sure to customize, so you get notified of local events that are of interest to you). Here’s why (from this month’s flash):
When you subscribe and/or customize your free MSDN Flash newsletter before May 31st, you’ll be automatically entered for a chance to win a grand prize trip to New Zealand. This trip includes round-trip airfare for two, 10-day 9-night stay at a luxury hotel, and a Lord of the Rings movie location tour. Plus, 150 second prize winners will be drawn and awarded a copy of the newly released Windows Vista Business.
The flash is free, and it contains TONS of useful information – such as links to new knowledge base articles, invites to free local events put on by Microsoft and other partners, as well as much more.
