PSA: Creating tags

In Why are there so little categories and optional tags? - #6 by vchuravy it is noted that we have only a few tags!

The list of tags can be seen here JuliaLang and I just wanted to remind everyone that if they have TL3 (e.g. they are regulars), they can also create tags.

I suspect only the author and mods (and maybe TL4) can add a tag to the post after creation,
but I would like to encourage the usage of tags overall.
