I am wondering if the tags should be cleaned up. I made a few several unsuccessful attempts, because I don't know how to delete or merge tags.
For example experiment is a tag with 5 hits or so, but no definition. It should be removed, or at least synonymed with experimental-design, if you ask me.
There are other examples, but I would like to know if it is possible to suggest such deletions. With less than 5 hits it is not possible to suggest synonyms, but that means that these needless tags keep in existence. Can anyone advise on ways to clean the tag list and get rid of largely unused tags?
