I use lingq for my French, I use other stuff too but lingq is one of the main thing so I was pretty >.< when I saw that they were down today. I’ve written a review of lingq http://www.languageninjas.com/lingq-review/
@jsq - Thanks for the review! Sorry the site had to be down. We were just upgrading the database and making other infrastructure improvements to enhance site performance. Short term pain for long term gain!
