There was a pilot program last November for ID mentorships:

I don’t know if there are plans to repeat. It would be cool if there was a program for matching folks more generally, but I gathered from the above discussions that it would be challenging technically.
I have done a little bit of informal mentoring in the past, and enjoyed it. Limitations: a) I’m not great on follow-through, and b) my knowledge is strongly limited to northeastern US plants and moths. But if you, or anyone, would like some assistance, I’d be happy to do so.
