Translation not properly enabled

Hi,

nice plugin! I would like to use it in other languages but the .pot translation file included with the plugin is somehow incorrect and cannot be opened and edited with poedit. The translation files downloadable from translate.www.remarpro.com are correct but only contain the back-end terms which, in fact, I do not really need to translate. However, the front-end strings which need to be translated for non-English users are not included!
Would you please correct the .pot file, add to it and mark as translation-enabled the front-end strings currently residing in the file
/wp-content/plugins/mass-messaging-in-buddypress/includes/implementation.php
The following front-end terms are in concern:
Subject
Message
Users
Select All Users
Groups
Select All Groups
Send as single thread?
Send Message

as well as the BP profile messages sub-navigation menu item name:
‘Mass Messaging’

All of them can be found in the above mentioned file …/includes/implementation.php
One could translate them easily in that file but would lose the changes after each plugin update and this would also not solve multilingual multi-site installations.
Best Regards,
Stefan.
