Tagging forum posts
Foreword: I hope this post isn't considered off-topic. If it's considered so then I apologize, and you may delete it. I know it doesn't strictly belong in the "Using GeoGebra" forum, but I couldn't find a more appropriate place to post this.
Just wanted to let you know that there's a browser extension that lets you tag posts on this forum.
Tags are different than bookmarks: you can associate a post with several tags, and the tags are displayed in listings as well. (They're certainly different than the one-dimensional "Bookmarks" feature already provided by this forum.)
Here are some screenshots (click to enlarge):
(I tag posts with 'kondr' if they contain juicy inside tips.)
(Here you see that tags appear in listings as well. Also in search results. BTW, I use the '_watch_' tag instead of subscribing.)
I'm the author of this browser extension. A couple of months ago I embarked on writing a technical document explaining GeoGebra (which I hope to wrap up and upload soon) and I needed a way to keep track of posts here; so I extended my already-existing extension to support this forum.
