The main rule that new Wikipedia editors fall foul of nowadays is that it's not enough for your information to be correct - you must be able to link the information to a particular source of adequate reliability.

This can be rather frustrating, as most of us know our specialist subject rather better than the books. But it's worth putting in the effort to source things properly.

Having your work edited can be a frustrating business, especially when it's wrong. Don't get angry about it, just build a case and remain friendly. And walk away from bouts of madness: people can get more than a little irrational about these things.
