"The great idea does not make a great story. A terrible idea with a good writer makes a great story" - this is
how Jim Butcher's Codex Alera was born. It was 2 horrible ideas - lost roman legion and pokemon - and it was a great story, in spite of the horrible
ideas. He wrote the books on a bet proving that
point.

Has anyone gotten it to work with CentOS 7.x? I get the error mentioned just login with admin / admin123 or add my own user and it just refreshes. Read the docs, if I want to just use 1 server the same one for both client and server is that supported?? The addserver scripts does not take "localhost" too kindly..

Thanks,
Tom
