Logging in
You can log into Jazyk by clicking on the big red 'Log in' button on the homepage.
You will be presented with the following screen (figure 1):

Enter your email address in the first field, your password in the second field and press the 'Log in' button. If your password is incorrect, you will see an error message (figure 2):

If you've forgotten your password, you will be able to reset it by clicking on the 'I have forgotten my password' link. A mail will be sent to your email address (check your spam folder) with a link to reset your password.

Once you're successfully logged in, you will see your username in the black navigation bar at the top of the screen.

You only have to log in if you haven't used Jazyk for an extended period of time. If you have to log in before that time, you have probably cleared your cookies, don't allow cookies from Jazyk, are browsing in private mode or are using a different browser/device.

If you want to log out, you can do so via the user menu (click on the user name) and click on 'Log out'.
