I just asked a question and added the tag [tag:source-code] but only typed `source` to get it. I then noticed that the tag [tag:source] exists, it has 83 questions and no wiki - should it be deleted?

No questions should have this tag, any question tagged with this can be changed to be tagged with [tag:source-code] or [tag:software-sources] or [tag:install-from-source] instead.
