CMS Made Simple Forums

This is probably a simple fix, but I can't find it. When I try and create a new user like "Joe Schmo" it gives me an "invalid username" when I try and create it. If I make it "JoeSchmo" or upload a csv file with "Joe Schmo" it will work just fine. I'm guessing this is something within one of the .php files that would have to be changed?

And I am using the latest version of FEU.
