Lack of interest [Suggestion] Disable/Enable Special Characters in Username

[Fufu]

I find it ugly (annoying) to have to list like below in the User Name Validation -> Disallow Words in User Names, instead of having a check box that says Disallow Special Charaters in User Names

You can do it with regex instead: http://stackoverflow.com/questions/336210/regular-expression-for-alphanumeric-and-underscores

Enter the code you want to use in the User Name Match Regular Expression field.
For example: ^[a-zA-Z0-9]+$

So would a-zA-Z0-9 restrict usernames to alpha numeric only?

Yes

Edit: Found this old post by Shadab which has a few more.

RegEx = Regular Expression
Some very simple regular expressions to limit the usernames are:

• /^[a-z]+$/i (only alphabets allowed)
• /^[a-z\s]+$/i (alphabets & spaces allowed)
• /^[a-z0-9]+$/i (alphanumeric characters only)
• /^[a-z0-9\s]+$/i (alphanumeric & spaces)
