Verb conjugation of "verbreiten" in German

My boss offered it to me, so that a few more people at work will have a good level of English and now I really have to kick my own ass (I've started last year and it's not going very well).
Thank you for your answer. Your correction in Russian has helped me. I'm glad to have found a Russian Vocabulix friend with Russian as the mother tongue. I will help you in Spanish, OK?
When I wanted to do my homework, I accidentally landed on Vocabulix and it caught me right from the beginning. Connecting with other users can be brilliant. Skyping with them, chatting and messaging. Great idea.
