stop. it's off-topic.
say how many time will spend on translation on the russian language.

The time spent on creating the translation depends on how quickly and well you can read english and convert the strings; I'd say probably a couple of hours or so to go through most of the files.

good, will be translates itself.
question: in case of the "BB buying.threads Standard License", i get access to all necessary files and corrections for a year.
how quickly does pass a process of buying, if will i pay for buying by the credit card?

It should take no longer than several hours; so long as it'd be purchased during business hours (as in not during a weekend)

ordered Standard License, a money from the credit card is taken off.
how quickly to expect completion of transaction?

It depends on how busy our accounting department is. They manually approve each one to help prevent fraud. You should be getting confirmation soon.

Let's suppose I was going to take a crack at the Russian. Should the files use Unicode or a Russian charset? I am hoping that PHP is Unicode-aware.

I'd say utf-8 if possible

Wow that's amazing. When you say manually approve - do you mean they just scan the (say) '3rd man' reports or they run credit checks?

Well tedious!

I believe they check every approved order to validate any fraudchecks
