Hello, Alexander.

It's wonderful that you wish to contribute to the Tatoeba project. What works best is if you mostly contribute sentences in your native language, the one you are most familiar with. I see by your profile that your native language is Russian and that you understand English well and Italian to a lesser degree. Tatoeba is therefore best served if you mostly contribute Russian-language sentences, which I see that you are doing (67 of your current 127 sentences are Russian, 19 are Spanish, 18 are Italian, 14 are English and 9 are Polish.)

At your request, I have offered suggestions for improving four of your English sentences — #3097659, #3099238, #3101207, #3103138. The other ten, in fact, seem like fine, natural English to me.

Likely, your Russian sentences are also fine, unless you perhaps misspelled something, for example. I don't speak Italian, Spanish or Polish, but other Tatoeba contributors who are fluent in one of these might like to take a look and see if any of them could be improved:

Because you understand some Italian and Spanish, and are nearly fluent in English, you are ideally placed to help translate sentences from those languages, and perhaps Polish, into Russian. Currently Tatoeba has over 545,000 English sentences, 337,000 Italian ones, 225,000 Spanish ones and 75,000 Polish ones. If you could help increase the number of Russian sentences from the current 278,000, that would be excellent.

Thanks again for your help with Tatoeba.

Best wishes,
Eriko Pedersen
