Change the output of _og_mail_text

I've searched all over and can't find a solution to this problem, no hanks in advance for any help!!

I really need to change the invite email text. I would like to change this text FROM:

case 'og_invite_user_subject':
        return t("Invitation to join the group '@group' at @site", $variables, $langcode);
      case 'og_invite_user_body':
        return t("Hi. I'm a member of '@group' and I welcome you to join this group as well. Please see the link and message below.\n\n@group\n@description\nJoin: !group_url\n@body", $variables, $langcode);

TO:

case 'og_invite_user_subject':
        return t("Invitation to join the  Team: '@group'", $variables, $langcode);
      case 'og_invite_user_body':
        return t("I am inviting you to join a Team: '@group'.  Click this link below to join the Team: !group_url\n@body", $variables, $langcode);

I know this is found in og.module, but the maintainers of this module have really helped out with rewriting the op invite functionality, perhaps they'd be able to point me in the right direction?
