Or should I be worried?? It's not the kind of dreams where I am 'me' sitting in front of a monitor.. It's the kind where I am the debugger tool running through code and more often than not, getting stuck in loops in code as I try to make small adjustments to try to exit the loop! Waking up can...

Hi all, While I have been coding with .net for 7 years now, I am probably still classed as beginner to intermediate because I never learned more than what my needs at the time of my projects required. I can still do anything I want with the knowledge I have which is the only thing that matters...
