Translation of bekifft

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.
I've also looked at the interface, and found it a good idea to include the colloquial option. Would it be very complicated to add the most important regional check box, like Spain, South America or Central America?
It's very good that you can learn English with the help of technology (Internet), I think you'll learn quickly. Although I am now getting better, I feel the improvement. But once again I lack vocabulary.
