Multilanguage messages - no everywere t("") in code

Hi,

I've just installed subdomain module with OG compability, and it works great!.

But some subdomain messages (warnings, like: "The ..... can contain only letters, numbers and spaces") don't exists in Drupal locale db). I checked the code and find that there is no t() function for error messages:

function subdomain_nodeapi(&$node, $op, $teaser, $page) {
....
  form_set_error('title', "The $type_name's $type_title can contain only letters, numbers and spaces");  // <--- no t("")
...
(and others below)
....
}

Best regards
