How does manual translitiration work? I didn't find explanation in any place?
At this moment manual translation is still in BETA version so it is not described on forum yet.
Shortly: you need to have appropriate usergroup (configurable).
Then you see button "Enable Manual Translation" with flags.
After enabling you can edit easilly - just move mouse cursor over text and click Edit button which will appear.
Also please see options in Admin CP -> vBET Manual Translations
