Not sure what you mean by locale or how to set it. I chose English during installation, if that is what you mean. The titles are all in English. My command of Russian is so little, from two years of it in high-school, more than 25 years ago, that I would never attempt to read anything significant in it
Thanks again for all your hard work - it is people like you (the REAL hackers as opposed to 'crackers') that make the computer community what it is.
