I received your reply and also replied to you back. Yes, I am only using the web version of LingQ. I signed up for a 90-day challenge in August and I believe that it will end this month. I am sure I have met individual goals for Listening and Reading but am not really sure about the Word Known goal. It is not a big deal but it is always a great feeling to complete 90-day challenges successfully.

edit: now I can see my statistics there must have been a change in the overall layout. Now I have to click under 90 days challenges and look for the one that I signed up for and under that 90-day challenge icon, I can see my current statistics for 90 days challenges. As per my previous assumptions I have a lot to catch for Word Known Goal.

Zoran, it is all figured out. Thanks for your help, though.
