So you've got birthday balloons by your posts in the fourms. And because it's the 26th where I am...it is your birthday. :] So, Happy Birthday and have a super day. (And tomorrow as well, seeing as it may not be the 26th just yet where you are).
I played fullback once as when ours got a knee injury.
I had no clue what I was doing. I had never played a back position before and was getting told what to do from the sidelines. It was pretty scary.
