Translation of twenty-six in Spanish

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).
If you do not want it, I understand since it is really little at the moment. But on the other hand, it is only 15 seconds to translate these short messages. Which link did you use? http://www.vocabulix.com?
Now I am learning by other means, such as reading and writing. I can not begin with conjugation training because I lack the basic knowledge. How are you learning at this site and which is your best lesson?
