Using flashcards on Iphone

I have been using lingq on my iphone since it arrived. I have finished working on all my lists and I understand that when you start a new lesson and add lingqs you could work them on your iphone; however, I have a long list of lessons with 0 words. How do you delete them?

@arenas - In LingQ, on the Lessons page, you should archive the lessons with 0 LingQs. Just tick the archive tickbox to the left of the lesson title. Archived lessons are not shown in the lessons list on the iPhone app.

Thanks Mark
