Scratch pad for writing forum threads / posts with markdown/markup

[Drone4four]

What do you people use for drafting long forum threads / posts / Stack Overflow questions?

For years I’ve been using Google Docs which I realize is not best practice. Punctuation like quotes wreck my code snippets.

Gedit doesn't do the job because I need an autosave feature. I need a Linux compatible solution which includes an English spell checker.

What would you people recommend?

Kate is the best editor for linux.

why not save draft posts, at least here on forum
