Hi Adam,
поздравляю Вам с новым сайтом!
Changing the language options is easy in WinXP. If you use Vista, it may be the same... not sure...
1. Go to Control Panel > Date, time, language and regional options > add other languages >
2. Then, under "text services and input languages," click on the button marked "detail."
3. Under "installed services" click on the button marked "add" and select Russian from the list.
4. Then at the bottom, under "preferences" click on the "language bar" button and check "show the language bar on the desktop".
That should give you a little box on the taskbar, right next to the system tray, that uses two letter abbreviations for the active languages. My default language is English, so the box says EN...

Polish is probably PL. Russian is RU, etc. Then, if you click on the box, you can quickly switch between input languages...

Надеюсь это поможет!
As for linkages between the new site and SC4D, I suggest a kind of gallery or announcement thread here, to let us know when something new has been posted at Sim City Polska and what the relevant details are...
