@capjamesg I just went through your blog and you're an amazing writer!

I volunteer for a couple of technical writing communities and I want to know if it's okay to reach out to you sometimes for maybe community hour sessions or just general interviews on technical writing.

I will also be sharing this guide in a newsletter that I write for the devrel community in Africa because it's so insightful.
