On-going:

Any sites created since then pay their own way, using their own accounts.
Faculty CU Blogs sites using domain names before July 2017 (grandfathered in)
Sites supporting special efforts or grants pay their own way, using their own accounts.
Departmental web sites pay their own way, using their own accounts.
