I just saw an e-mail that says Microsoft is having a “fan drive” to get fans of the Microsoft Patterns & Practices summit on their Facebook group. You can go to the P&P Summit Page on Facebook and become a fan. On the page there is this description of the summit.

If you're a software architect or developer who is passionate about mastering your craft, you should register now to attend the next patterns & practices Summit, October 12-16th on Microsoft's main corporate campus in Redmond, Washington, USA.

According to the e-mail if the group reaches 250 fans by the end of the month a random (non-Microsoft) person will get a free pass to the summit. I just became a fan and there are 67 fans now.
