About localization

System is already partialy translated to Lithuanian (windows-1257) so u can see some unknown records in pictures.

Yes, now I see.

All these messages can be edited through the administrative interface.
Just go to the Settings page and chose Information Blocks from the drop-down list for modifying the menu items (this menu item are dinamically added when you specify Information Block types).

As for the Menu types - they can be specified also in the Settings - Structure Management.

Hope it helps.
