Thanks to member Catja for the suggestions about how to improve the tagging approach used on BooksWellRead. I’ve made both changes she suggested. First, when a user submits a tag ending with a comma, that comma is automatically trimmed. Second, users can now enter multi-word tags but connecting words with an underscore. For example, if you want to tag a book with the word pair “funniest ever”, type “funniest_ever” in the tag field.
