I started mentoring in one of my Discord groups originally and as time has gone by, I opened up to more- thanks to @davemccoy.

I have five people in one Discord group that I speak with on a weekly basis plus I have a fostering program/post where I take one gardener for a week and mentor them too; plus this initiative.

It can be difficult sometimes to find enough people to mentor versus the number of people that want/need advice. But over time I foresee this opening up and more people getting involved.
