Please follow the following guidelines for your writing:
The language of the Handbook is American English.
Please use gender-neutral English whenever possible. Refer to people as "they" and "them" instead of "he," "she," "him" or "her."
Write short sentences.
Introduce enumerated lists (like this one) with a little bit of context (as in the previous paragraph).
Beware of common grammar mistakes in written English.
Use a spell checker before committing your changes.
