1. My principal blog "Little Baby Jaysus" has two urls 1977redux.mlblogs.com and littlebabyjaysus.wordpress.com
2. My secondary blog "Portage Artist" with url portageartist.com matches my wordpress username "portageartist"
3. My principal blog"Little Baby Jaysus" requires a matching username. Its current display name is "Little Baby Jaysus" but it operates under my one general username "portageartist"
4. I need to change that username to littlebabyjaysus. When I tried to do that I was told "sorry that username already exists" most likely because I already use it as a display name and url
5. Please help me match my url to my username + display name
The blog I need help with is 1977redux.mlblogs.com.
