Re: [support] getting the underscore to be unusable in user names

I have run into trouble with the underscore. (concerning a mesh up between drupal and mediawiki)

I would like to find a way of getting the underscore on the "banned list" for drupal registrations. If I try and register a name such as "great!!!", I get a message saying:

"punctuation is not allowed except for periods, hyphens and underscores"

I would like to make it impossible for underscores. Is this just a case of altering something in user.module?

many thanks in advance

Look up hook_user on api.drupal.org

Write a small module that implements the 'validate' operation.

That way you can make your validation and not have to hack the code.
