I don't think you can do it manually. I've seen several sights like this, and you would want to email the mods, admin on this. They are rather quick to respond, They responded to a problem I had yesterday (but I was fairly quick to figure it out, I'm good when I'm frustrated )
Good to see everyone's names worked. Just keep in mind it's not hard to change your names but if everybody asks for it it will get confusing for everyone. It's best to get one and stick with it, so hopefully you will be happy with these for a while.
I have been off and on lately being busy up to my neck in something big I have been working on, so if I'm not on to answer questions that's why.
