Post History

One of the benefits of Codidact is that each community can use tags in the way that best supports their community. For example, Judaism supports hierarchical tagging for references, different tagsets are available for different categories, etc. 

Meta's tags are mainly used as a way for the site builders and administrators to keep track of what is completed or not, thus the required tags in some cases. Other sites may not want mod-only tags, and _we do not wish to force a particular schema upon the users of those sites_. 

- Mandatory - May not be relevant for a community at all (no mandatory tags exist)
- Mod only - The singular moderator role is in the process of being replaced by the trust level system, and some tagging privileges may be tied to that eventually. Otherwise this is relatively unusual. 
- Lower case - I think we have proper nouns for some tags, this may not be ideal
- Character number limit - I believe this is already limited
- Tag number limit - Why? The languages supersite proposal, for example, may have hundreds of tags for different languages; I don't think there is any benefit to cross-site limits based on currently existing use cases
- No spaces - already enforced, you get an error
- Disallowed characters - already disallowed by definition, I don't think we have any reason to forbid the use of symbols. 

If you wish to see the tags used in a particular community you can check the "Tags" button below the category ribbon. We will likely add additional help topics in the future and possibly change some of the ways that tags are assigned, but for the moment any inconsistencies between sites do not appear to be causing harm (though please bring examples otherwise to our attention).
