Prevent quotes in names!

[stefaandk]

I want to prevent certain characters from being used during username registration.

is it as simple as placing these characters in the "illegal user names" options in vB options?

Thx

Unfortunately not at the moment, it has been implemented within the next major version though there is no release date for it at the moment. There may be a plugin over at www.vbulletin.org to perform this functionality in the current version.
