Hi. I've been working with SharePoint since August 2007. I was an "end user" from August 2007 to August 2008, and then left SharePoint alone for a while. I decided to go at it again (this time as an administrator) in April 2010. As of December 2010, I now have my Microsoft Certified Technology Specialist (MCTS): SharePoint 2010 completed. I'm currently working on my MS Information Technology Professional (MCITP): SharePoint 2010. After this, I hope to move on to Development and eventually become a Microsoft Master (MCM) in SharePoint 2010 (or 2013, whichever!).
I've got a strong history with Active Directory, SQL Server (both SQL code and server management), Windows Server NT 4.0, 2000, 2003, 2008, all versions of Windows client since 3.1, and numerous attempts at dabbling into various programming languages. I also have some experience with Solaris 8 and Solaris 10, however my time spent with it was brief so I doubt it would be useful here.
I understand that even when people know a lot about a topic, they don't know EVERYTHING. And that's why I like about Expert's Exchange, as it gives IT professionals (and learners) a wonderful medium to swap information with each other!
