Translation issues

First, I'd like to say thank you for this very promising & exciting project. Hope it will develop further, though it's already an excellent decision for site gallery. Good job!

Now to the point: I'm having problems submitting my own translations:

 So here's the error:
@todo TRANSLATIONS_SUBMISSION_FAILED HTTP/1.0 400 Bad Request

File: modules/gallery/helpers/l10n_client.php, line: 188
And here's how we got there:

    * modules/gallery/controllers/admin_languages.php [55]:

      l10n_client_Core::submit_translations(  )

    *

      Admin_Languages_Controller->share(  )

    * modules/gallery/controllers/admin.php [50]:

      call_user_func_array( Array
      (
          [0] => Admin_Languages_Controller Object
              (
                  [theme:private] => 
                  [uri] => URI Object
                      (
                      )

                  [input] => Input Object
                      (
                          [use_xss_clean:protected] => 1
                          [magic_quotes_gpc:protected] => 
                          [ip_address] => 
                      )

              )

          [1] => share
      )
       )

    *

      Admin_Controller->__call( languages, Array
      (
          [0] => share
      )
       )

    * system/core/Kohana.php [291]:

      )
      , Array
      (
          [0] => languages
          [1] => Array
              (
                  [0] => share
              )

      )
       )

    *

      Kohana::instance(  )

    * system/core/Event.php [209]:

      call_user_func_array( Array
      (
          [0] => Kohana
          [1] => instance
      )
      , Array
      (
          [0] => 
      )
       )

    * system/core/Bootstrap.php [55]:

      Event::run( system.execute )

    * index.php [72]:

      require( system/core/Bootstrap.php )

I noticed that everything goes fine till I change "No comments yet. Be the first to <a %attrs>comment</a>!". I tried several times already (deleting DB entry->submission ok; adding this string translation "Еще нет. Будьте <a %attrs>первым</a>!" ->error).
Is there any way to overcome the problem?

Also, I noticed that many strings are hardcoded (like "Add a comment" in ui.init.js, overlay menus, strings like "Advanced" in main menu etc). Is it possible to also make them available for translation?

And last, but not least, I’m pretty much interested in translating to mother tongue. Is it possible to add more languages to the list (mine is "Belarusian", just in case ;)?

Thanks!

Dear bharat, thank you very much for your kind response.
Just a quick note re Belarusian locale: it is actually be_BY.UTF-8. Correct setting below:

$l["be_BY"] = "&#1041;&#1077;&#1083;&#1072;&#1088;&#1091;&#1089;&#1082;&#1110;"; // Belarusian

tried github, hope did it right

Thank you!

@unostar:

the issue with localizable strings with "<a %attrs>" is now resolved. it's a server-side (gallery.menalto.com) fix, so you should just try to resubmit your translation and it should work now.
