Add a Discussion catagory for sharing custom CSS

I don't code myself but I'd be cool to see what others have come up with for those willing to share.

This sounds cool. Just a discord channel would be enough for people to share Thier creations.

LKD70 We have a discord channel #appearance where people have shared their custom CSS

A community member also started a subreddit, which would be nice to see people contributing to: https://www.reddit.com/r/KagiUserCSS/

z64 Cool I should link this in FAQ.
