My nominations:
Most posts?
It's a flip between Whabang and Blobrana. Hell, let's just award something to the pair of you... You've both made me laugh my socks off and have been an education too.
Best Avatar?
Karlos. The anvil/poster/sock one still has me chuckling. Blob's Spitfire avatar was good.
Most impressive picture?
X-ray and his gatling gun. I want one of those bolted to the front of my car, together with a gunsight on the dashboard...
Scariest Post?
Hmm, there's many. I think Bloodline's frank admission about his sox life was quite scary, although Blob's contribution to my "Confidence" thread was a prophecy that thankfully did not come to pass. The political ones are usually scary in some form or another but for slightly more serious reasons.
Best biking related avatar?
Me.
