* The scammer wants you to wire them some money BEFORE sending the check,
or
* They send a check for too much, and want you to wire back the difference. The check later bounces, and you lost the money you wired.
The woman says she is sending the check after she "hired" me to do work. She said this is my "paycheck" but yet I've not done any work so far for her. It kind of worries me this could be a scam, but I'm not sure how to find out if it is or if it is legitimate.
