Hi Andrey,
Privacy Level DropDown has an issue in the currently released version and you can read more about this
here. Silverlight upload module localization will be available in next release that should be delivered very soon (I hope this week). I'll notify you when we release new version of MonoX and will provide you with details on how to localize the Silverlight upload module.
Can you provide us with a list of modules where you want to perform the localization of Silverlight upload module e.g. Discussion board, Photo gallery etc. ?
Regards
