Illustrator is quite simple. Just go thru the exercises/tutorials that come with your software. Or just drop by any book shop and get the 'Dummies guide to...' (Despite the name I think its quite good esp for beginners). Hope this helps
i have use this program for my work since 1997. not an expert but ok to earn my keep with this knowledge. The best is if there is someone who can teach you on the spot and show you the basic moves.
PM me if you are keen, i'm meeting Sam aka nightwolf75 on Wedesday, if you can hang around until 7pm i can show you a few basic steps on my laptop at SEED?
