Have to write this in English (sorry, don't have Ru-keyboard handy). We'd like to start with including a Russian language file with default Dolphin package. We normally don't include extra language files, because we can't support them, but we can support English and Russian.
So, we'll be posting a request to members to submit a Russian language file for assessment and inclusion. IF you have one that you have the right to distribute, maybe you'd like to share? Good thing is that it will be supported in future versions and updated by BoonEx.
As for Russian documentation... Absolutely, we can start adding whatever is submitted to Trac and can go from there. Any input is welcome.
