I tried to login on Polina's barefoot diary with the same data I login here and do not work.

So I tried to register on "the diary" with the same login data but it fails,it warn that username Clipper is already in use.

For go on I registered myself ,on Polina's barefoot diary,with another username "Clipper2",it worked only one time,now I can not login any more....

There is some way to login on Polina's barefoot diary with the same data (username and password) that I use to login here ?
