If you used to have an account in this forum (when it was accessible at “https://sourceforge.net/apps/phpbb/mumble/”) you will have to use password recovery to reset your password to be able to use your account again as we no longer use the sourceforge account system.

When resetting your password you will have to enter your username and email address. The username to enter is your sourceforge username, and the email is yourusername@users.sourceforge.net. Be aware that your SourceForge account settings have to allow emails from us like in the following screenshot (red circles):

If you are in doubt on how your account is configured make sure to verify first. Otherwise your recovery email will be rejected and we won't be able to send you another for 14 days even if you fix your settings.
