@cbowdon Imagine what I'd think looking at code I wrote in 1995--that is still being used at my old company. :)
No worries when it comes to mentoring. It's less about what you know than it is about genuinely wanting to help them, and your experience in problem resolution is really what they're after, not just coding specifics.
Mentoring is probably my favorite part of this job--best part is keeping track of your "project" people as they develop their careers.
