I'm looking at the user module because I want to implement a login feature on one of my web application. More specifically, I'm looking at the restrictions: http://docs.basex.org/wiki/Valid_Names#Valid_Names

For web applications, it is very usual for people to use an email as a username. The restriction on the period character is very annoying in that regard.

I understand why it's a restriction on database names, but for user names it creates a limit on the ability for less frequent users to access the site. Most people remember which email they used or have only 2 or 3 to try. Passwords are saved in keychains. However, remembering a username... pfff!

Is there any way that the restrictions on user names could be adapted to allow for characters that are valid for an email address in the near future?
