I guess there is a problem with the site. I cant see who is logged in. I feel  like a bat Please someone fix it.

at me, too, was a problem since 2 days ago...it was impossible to sign in here..

but I am happy is working again

Yazdığın derslere yorum gelince haberin olamıyor da. Tek tek bakmak zorunda kalıyorsun. (You also can´t be informed when a comment comes to the lesson you have written. You are obliged to look one by one.)

Do you still have this problem?

i had the same problem, but now everything works.
