Translation of rapero

I will add a feature to the dictionary builder tool, that marks a word as vulgar. The words that are shown in the tool are words that users did not find in our dictionary and a lot of them are vulgar.
Somehow, my email was not sent. There were even a few mistakes, but really only minor things, nothing really bad. I've already read some other texts that you have sent and are getting better each time.
I have problems with adjectives, endings and articles. The grammar is so difficult. I am very happy to learn Spanish with you. What went wrong with the lessons? Thanks and best regards.
