If any repo watchers have any tips for this process, let me know.

Can you add this translations?

Here is russian *.po and *.mo files.

@r-a-y updating text domain should be enough for this transition?

@AiratHalitov - Thanks for your translation, however the plan is to move translations over to translate.wordpress.org so I do not have to bundle language files into the plugin anymore.

@mustafauysal - Thanks for the PR.

I think the next step is modifying the load_plugin_textdomain() call and syncing the plugin to plugins.svn.wordpress.org so translators can start using translate.wordpress.org to independently update their locale strings before v1.3 is released.

@r-a-y
When will v1.3 be released? I'm looking forward to your plugin updates. :-)

@r-a-y take a look please: #89

@mustafauysal Congrats! :)

@r-a-y Could you add me as an editor for the pt-BR? Or are you going to import it (not sure if it is possible, just curious)?
