Anyway, I will add the 'offending' word feature within a few hours and write you an email once it is up and we will give it a try. Do you agree? Did you get my message? When do you want to start translating for me?
I signed up at Vocabulix long time ago and I did not use the account, I even forgot it. But I am always remembering it when I receive newsletters or when I am contacted by other Vocabulix users.
