I'm not much of a rule reader when it comes for cooking. I tend to see a recipe I think looks good, read the ingredients and jump into making it. It generally works well for me, but drives other people crazy when I give them a recipe and it doesn't taste the same when they make it.
As for the forum rules, it seems pretty self explanatory. Post things in the right category, no copyright violations, etc. I never read the how to post a picture; I just clicked attach files. This board is so well set-up there is very little need for instructions.
