If I like the book I'll write in the margins. If it's a second read lots of stuff let's put there, lots of spoilers.I only really use pencil unless I'm copying something directly from another source and want it for reference.I'll sometimes make pencil marks in library books. No spoilers or anything, but amusing notes to future readers. I'm a monster.

@ElsaPreme@chaosfem.tw Can it be DCF77[1] instead? Or whatever the local equivalent is (WWVB[2] is the North American equivalent)[1] https://en.wikipedia.org/wiki/DCF77[2] https://en.wikipedia.org/wiki/WWVB
