I just passed 070-284 Implementing and Managing Microsoft Exchange Server 2003 which gives me my MCSA. I've been taking Microsoft Certification tests once a week, hoping to get my MCSE +Messaging before we go away. My contract with SRK Consulting ends the day we leave, so I'm hoping to make my resume look a bit prettier for when we get back. I'm not a big fan of a lot of certifications because there are so many people that just read a book and take the test without ever touching the technology involved. The problem is that a lot of HR departments use the MCSE as a filter when hiring.
Correction: Actually received MCSA +Messaging, and MCSA. Now have four certs (MCP, CCA, MCSA, MCSA+M)
