Post History

Do you want any special tag styling or requirements?

Codidact allows you to define three special *types* of tags:

- topic tags: these are treated as ordinary tags in all respects except that they're styled differently so they stand out.  You can see examples on [Photography & Video](https://photography.codidact.com/) with the "photography" and "video" tags.

- required tags: a set of tags, at least one of which must be used.  The "discussion" etc tags on meta are like this.  They're styled differently *and* you must use one.

- moderator-only tags: used on metas for the status tags; you probably won't need these elsewhere but I include them for completeness.

I see that all of the posts (so far) in Challenges and Sandbox are tagged "code-golf", and presumably other challenge types would be tagged by their types (bowling, KOTH, etc).  Do you want those to be special?  If so, which type of special -- topic or required?

If you want any of this, we can make the change at any time -- no rush.  If you choose to use required tags, the requirement will be checked for new questions or when questions are edited, but old questions that don't have them won't generate errors.
