I'm a best man.... is that a good thing?

I have the unfortunate pleasure of being a best man for the first time ever to a close friend of mine called Rob. Whether this is a good thing I don't know yet, but it is only made worse by him being the first of our circle of friends to get married so i've got nothing to go by to find out what I should be doing.The reason I mention is that while searching the web on tips and hints on what the hell i'm suppose to do etc I can across a good ColdFusion site that I'd thought I would share'm now going back to see if this a like Jury Service and there's now way out or not. Only j/k if you're reading this Rob ;o)
