Nice attempt @keecee .
Tags are not only names of communities. They are topics we used to publicize our posts to the right audience. If I write a fiction story, I can use fiction and writing as my tags. Or if I'm running a giveaway, I can use giveaway as one of my first tags.
Anyone looking for fiction story to read will easily find it by searching with the fiction tag.
Just take your time to explore, you will understand everything as time goes.
Well done on your 4th task✅
Thank you ma
