To check how this works, I found one of my own photos that has one comment by me.
I deleted the photo but my comment count still stays the same.
so it seems to only update comment counts after I would run the process.
I just want to update the user name. I'm trying to gradually change users names who still participate in the weekly contest to make sure they have no spaces in their user name i.e. first last, I change it to firstlast
I'm doing this to match all the tags I am giving winning photos potw-username, potm-username etc.
