I wasn't able to get much out of the workshop first time around mainly because my home life suddenly became so complicated towards the end of the summer. I have now settled into my own place and can now spend pretty much all of my free time doing what I want, when I want, so I am getting back into this C# thing.
It was/is a great workshop and I shall be starting it again from the beginning hopefully sometime just after xmas. I am currently studying from a series of video lectures which are geared more towards my present level (XNA Xtreme 101 Volume 1: Intro to C#/XNA from 3dbuzz.com). Well worth a look if anyone else felt the workshop went a bit too quick for them to keep up.
Anyway, I'd best get to bed. Thanks again JWalsh & everyone else for all your help so far. See you after xmas :)
