On a personal note, the most important posts to me personally this year were:

KWSOP Cancelled - a friend sent me the email for this, and my curiosity into the legal side of things brought me to the forum. Prior to this I rarely played poker (maybe a few times a year) and was totally clueless. This sad day actually sparked my "poker career", so at least some good has come of it.
Free Friday Night Game - my first post. Here I learned that poker isn't "for fun" - get some $$$. :)
Bristol 'Easy' Poker Bash - my first tournament after starting to read/play a bit more. Here I started my journey into the giant web that is KW poker.
KW Nameless Holiday NL Tournament - my first tournament which started my hosting career in KW. Luckily I had Zithal to train/mentor me, so things started a lot smoother than I expected (thanks Rob - this Padawan appreciates it).
500th post - a sad post really, and I didn't notice it was my 500th till JohnnieH PM'd me later. If I'd known, it would have been better (honest)!
Ryder Cup Kitchener - captain's picks - I was very surprised at being selected at all, and especially this high. One of the high-points for me so far.
