Taping Cement Board Joints

Question

I'm confused about whether or not to tape the joints on 1/4" wonderboard, a cement backer board for tile. The manufacturer says not to, but people in the trade say to tape them with fiberglass drywall tape. Any insight on this would be greatly appreciated.

Answer

Actually James Hardie recommends the use of a 2" fiberglass tape embedded in thinset mortar to tape and mud the joints.
