I keep thinking about Mentoring, but I am on so sporadically. >.>
You never know, until you try, MM.
And if you try, realize that it's not for you for whatever reason and step down, nobody will curse you.
Mentoring is not for everyone. If you want to, feel free to PM any of the mentors and ask the questions that concern you.
And you can be active in the Intros even without being a Mentor - the Intro boards are the largest chunk of the time dedicated to Mentoring for most, I dare say.
