Rita lives in Toronto, Ontario. She recently discovered that someone using the initials "AB" posted comments that are defamatory of her on a website called "CheatersandLiers.com".

CheatersandLiers.com is owned and operated by a company located in the United States. The posting states as follows:

"Rita is a horrible person. She lies constantly. Rita is a manager at a clothing store where she treats all the employees like they are her personal slaves. She yells and screams at them for no reason. Rita steals from the store by taking home items that she claims she is borrowing but she never brings them back and never pays for them."

Other than the "AB" initials, there is no information on the website that identifies the person who wrote the posting. Rita believes the posting is false. Rita does not "lie constantly".

While she works as a manager at a clothing store, she treats all the employees with respect and never raises her voice at them. She does not treat them as her "personal slaves". She never takes any items from the store without paying for them first.

Rita has written to ChearsandLiers.com notifying it that the posting is false and defamatory and asking that the posting be taken-down, but the website has refused to remove the posting.

Rita wants to sue AB and CheatersandLiers.com for defamation but she does not know AB's identity.

1. In addition to the legal process, what practical steps does Rita have to take to identify the poster?
