I guess the only kind of mentoring I've done, not sure if I'd call it that though, was nominating people for #pifc. I had to skip doing that for a couple of months but I plan to get back to it. I liked looking for new people to support.
You made that offer to me, to sponsor a contest, but I don't have clue one on how to do that. And I probably wasn't ready at the time to give my full concentration. (I think the pain meds made my brain foggy!) If you are still willing, I am willing to learn! (The idea you suggested was along the 'how we met' line.)
