• I've add the placeholder "john_smith" into "Username" input
• I've add the text: "Please enter the name you'd like to display to other users to identify your contributions." under "Username" input.
• I've changed the rule to reject the "@" character in the input and I've deleted the "@" in the error message (now it's "Letters, digits and ./-/_ only."

We need to wrap all strings with gettext so they can be translated. Either like {{ _('Please enter the name ...') }} or:

{% trans %}
<p><small>Please enter the name ...</small></p>
{% endtrans %}

Sorry groovecoder, I've messed-up with the vendor thing :S I'm going to close this pull request and send another one because I don't know how to update the submodule in my branch... (I've tried lot of things unsuccessful :S) so I think It's going to be easy create a new branch and pass my changes to it...
