I would also add to this that if you're writing for an international crowd, which may include many people who speak English as a second language (a really fast-growing segment of the world population), avoid phrasal verbs and idioms.

ex. phrasal verbs: sign up, go over (Usually a regular verb with a preposition attached. These don't exist in most other languages and can be confusing.) In the case of these two verbs, I would replace with 'register' and 'review'.
