In the DLDB where it shows the Author, it doesnt change along with your name, I was wondering if it could work like the list in stats does, so when you change your name all your maps are under your name. For me it isnt a big deal from 7-7 to Mp)7-7, but other people that change their names completly. Just a thought
It saves an SQL query not to do that, so I'm assuming the author was just conserving resources with that one.
I ran IPB's tool to "reset the saved usernames in posts, topics, logs, etc.". I doubt this will affect the DLDB, however, as it is a mod.
