Gnus Part 1

| Comments

I’ve picked up something this time which I’ve always wanted to study properly – Gnus. The Emacs news and email reader. This is going to be a multipart episode since Gnus is so big. I don’t know how many exactly but as of now, I’ve got a 3 part thing planned.

Also, the hiatus was unexpected. Things should be smoother now.
