Mentor vs. Supervisor, Which am I?

I am neither my mentee's supervisor or boss. I am just her colleague trying to help her achieve her goals in learning technology. I see myself as her mentor but I find it difficult to formally evaluate her process in achieving her goals. Most of my job right now is to coach her along in the process. I do see her attitude changing slightly toward the usefulness of technology. She seems more open than ever before to our laptop program. Not only does she seem open, but she seems like she will be a willing participant. I think this will help her to learn more. I am still waiting for her to go to the email class before I bombard her with finding out her username and password. I want to see her desire to use the email before I overwhelm her with all the details.
