How can I add someone to the white list?
Go to https://horde.metu.edu.tr/login.php address and login with your username (e******) and password. If the language is not appropriate for you, choose the language from the “Dil” drop-down menu. Then, click on the “Giriş” button.
From the menu on the left, click on the "Options" button. A sub menu will appear under the options button. Then, click on the "Filters" button.
From the menu on the top, click on the "White List" button.
You will see a textbox. Click inside the textbox. Now, wright down e-mail addresses that you want to put in white list. (Be careful: You should write all the e-mail address on separate lines.)
When you finish writing e-mail addresses, click on the "Save" button on the same page
Changes are saved. E-mail addresses are on the whitelist.
