Thank you for your kind and welcoming message @kaiod 
I just added the description to the tag and hopefully that will encourage more people to make use of it!
I really look forward to collaborating on everything that has to do with Tor and education, I’m very reachable so ping me at anytime with all the ideas you have! I will actually open a forum topic now to get input on something small I’m working on.
As for creating new categories, to be very honest, I don’t have any clue what’s the criteria to have a category vs a tag, but from what I understand categories are very general and tags can run through many categories. So “Education” can be a part of a “General Discussion” or “News” or even “Feedback” 
In any case, I will ask about it!
