Translation of abschäumen

I have studied French for many hours per week, and I've even lived in Geneva for a while... my French was good than. Today, I have forgotten most of it. I have to re-learn and Vocabulix can help.
In order to quickly become successful, one would have to change certain points, at least in my opinion: After 5 months of learning, I have still not found the grammar practice on which I should concentrate.
Absolutely no problem, do you speak English? I'll help you to learn it and you will like it. Your English is really very good, I understand all your lyrics, and please accept my friends request.
