We are sorry for inconvenience. You possibly have a problem with browser - fonts for cyrillic dosn't installed. If you are using Windows check this out Russian in Windows 2000/XP section "Activate Cyrillic Support" is enough to make your system recognize cyrillic letters. You can also install phonetic Russian keyboard layout if you want to write, too.
Your problem rises the question, that I always shifting into background as of thingink, not so much users we have without preinstalled cyrillic.
May be it makes really sense to translate all our forum to fully universal coding - UNICODE, that will allow everybody without any installation see all kind of letters, like Armenias are now visible, independently which browser, system or coding one uses
