I'm not sure if Marck has contacted you yet, but the best course of action is to do the following, until we've developed an in-house Facebook-like tool for translating stuff and getting the community to review it (if you've used something like that in the past).
1) Make a new folder under the "lang" folder for your language, using the proper 2-letter code (ru?)
2) Copy the contents of lang/en/ into that new folder
3) Add an entry for your language to lang/locales.txt to make that choice appear in StencylWorks's preferences
4) In StencylWorks preferences, switch to your language.
5) Now, translate each phrase over and then test in StencylWorks to make sure it renders properly.
That's the basic procedure. When you've got something workable, attach the translation here as a ZIP, and we can talk about what's next.
Thanks!
