Only bringing this back up because I wasn't able to create a Display Name containing a space in 7.6.1.1 unless I enabled "Allow Special Characters In Display Names" -- so unless there's a new bug, or the definition of "Special Characters" has changed, this wasn't actually resolved...?
(Member had a problem registering but she didn't know what the problem was -- I tried manually and got the "no special characters" error. Turned that option on and it worked. I don't want "special" characters in Display Names, but spaces should obviously not be "special")
Thanks...
