Hi, it sounds like those are tags you wish to nominate, since they are not already in the tagset. You are free to nominate them using this link: https://archiveofourown.org/tag_sets/13351/nominations/new

Once they're approved, because of caching issues, you may not be able to signup for them right away. In that case, you'll need to comment here with the exact characters and fandoms that you're having that issue with, and we can batch load them on the back end.

Let us know if you have further questions!
