Category Comments Function Back In Operation

Well,  I just created new categories,   used the same theme,  went back and got the dates of the things I had posted to them,  added the comment tag to each of the new category’s itemTemplate, and all have working comments now.   I deleted all for the former categories once I copied all the posts to the new ones,  which was easy.  All I had to do was: While both Categories were still alive,  the old one being renamed to old whatever,  then I just edited the old post,  checked onthe box for the new category to put it in,  and it gets added to the new category in the right timeslot.
