What sort of guide/tutorial would you like to see?

[Mzzkc]

I have some writing time on my hands, so I figured I'd start work on another guide. Problem is I'm not sure what people want to learn about that hasn't already been extensively covered. Hence this (non-public) poll and emphasis on style. Let me know if and/or what you're interested in, and I'll see what I can do. Worst case scenario: no one cares and I can start work on a larger project. Cheers. Edit: Oh, please let me know where you're at in terms of experience (in the given topic) and what 'level' of info you're looking for. e.g. beginner, intermediate, advanced... It'll give me a better handle on what the audience is expecting. Editt: For those who don't know my previous work, or my qualifications, just click the link in my sig. Or whatever.
