Post in forum #265727 - [Announcement] Tag categories for existing tags can no longer be changed via metatag

NotMeNotYou said:
As the title says we have just pushed a change that the category of established tags can no longer be changed via metatag (artist:, etc) but instead has to be changed via editing the tag itself. We have also added a new moderator action to keep track of who changes what tag category.

If you wish to change the category of a existing tag now please edit the tag on our Tags page, linked at the top of the page.
The process is straightforward, go the page linked above, search the tag you'd like to change (the search field supports wildcards), and click edit besides the tag you'd like to change. Then simply select the new category and save it.

If a tag's category is locked and you're confident it's wrong please contact one of our admins and we'll have a look.

I'm not understanding the technolingo used here.
