On a completely unrelated note, I was looking at a somewhat complicated Wikipedia page yesterday and noticed a piece of text I would like to edit. It had some stuff (citations and references) I felt I didn’t understand how to edit without being sure I wouldn’t break anything. Is there a good forum or place where I could ask for help with my edit?
1. preview changes until the result looks the way you think it should
2. have faith that if you broke something non-obvious, then the WikiGnomes will fix it (and then you can look at the page history and see the change and learn)
3. be bold! If you've never had an edit reverted you aren't contributing enough.
