Users who do not wish to receive the site newsletters and alert messages, can unsubscribe from them by following the instructions at the bottom of such messages.
One way to unsubscribe from a mailing list is to send a blank message to an address mentioned at the bottom of the mailing list messages you receive. In response, the site will send you another message with the URL of a special page that you need to access to confirm the unsubscribe request.
When unsubscribing by e-mail, make sure you are sending a message from the same e-mail address used to subscribe. Otherwise, the site may not find your account and your unsubscription request is ignored.
Note that there are several types of mailing lists. Users can only send one unsubscribe request by e-mail at a time.
You should get a message with further instructions in response to your unsubscription request. If you do not get the message in 24 hours after you send your request, please contact
the site administration for further assistance.
An alternative way to unsubscribe is to log in the user options page
and uncheck the options respective to the mailing lists you are not interested. This way multiple list can be unsubscribed in one go.
