Registration does not work in Opera 12

When signing up, clicking the submit button on the form changes it to "Joining...", but nothing happens. I left it for 10 minutes and nothing changed.

Whether or not you consider this an issue, I don't know, as there is a newer Opera version. Many users of the old version, including myself, are not switching yet due to lack of features that this version has (>12 is a fork of Chrome, meaning everything must be redone).

The issue reports that submitting the registration form in Opera 12 changes the button to "Joining..." without completing signup. No files, tests, or entry points are named; start by reproducing the registration flow in Opera 12 and tracing the submit behavior. Done means the cause is identified and registration works in the supported browser scope.
