I'm using WP multisite feature to support both Russian (skycase.ru) and English(skycase.pro) versions of my site.
I've got one shared user ashiyanov on both blogs which name is "Artem Shiyanov". What I want is to make his name "Артем Шиянов" on the RU blog.
Currently I use the plugin "Multisite User Management" to share the users and "Multisite Language Switcher" for translation/mapping pages.
The simplest solution would be to have different users for different blogs.. But it not only un-handy, but it doesn't describe the reality well - ashiyanov is really one single man.
