i see. though, i don't really get what you mean about "normal tagging". Sorry. while that's true that H has a lots of tags and would be hard to be implemented. but at least it would be fun and really helping if the vanilla are there.
that being said, i think it can be done if MD have "add custom tag" and "tag database" that can be use to make reference and keep reference information fo what tags are for what, for the tags that have been made by dev or the community. seeing how much the demand is for new tags. just an honest opinion and suggestion to grow the site.
and thanks for answering>
p.s.: hope we got a notification of the forum we're in aside from the person tag
