I have written an improved flagging guide, I remember people complaining about visability of text on the previous one, so I made this one a little simpler in terms of looks, so I hope that helps. I have also thrown in a quiz to this one! Kidray also pointed out in his review of my last one that I missed explination of some obvious things, so I hope they are covered here.
I would have edited my last one but I lost the fla, so I spent sometime throwing a new one together, sorry if it seems a little bland. Anyway, there are some tips and everything here for you.
