Which one?
Was quite some time ago, I'll have to find it. Wasn't a big thing, just a doc edit. (I'm a book editor.)
I think it's a huge thing. Worth finding and wearing as a badge of honor. "Bitcoin core contributor". Even if just fixing a typo, it shows that you've contributed towards making Bitcoin better. Mad respect.
Thank you. I sort of forgot about it, but I do feel good for having contributed to something larger than self.
