With the "Mail" feature of MtZion.net, you can send and receive private messages (PM) to and from registered users of the site.  In order to access your mail account, you must first be registered with MtZion.net.  From there you can see the link in your Dashboard menu at the top.  While in Mail, you can compose new messages, check messages that were sent to you, delete old message and change your mail notification settings.

Your Mtzion.net Mail account is great for communication with fellow members of the site, however it is limited to MtZion.net.  You cannot use Mail to send emails to external accounts.  Mail messages are limited to 2500 characters per message due to server limitations.  Messages in the trash can are automatically deleted after 1 day.  You may also block communications with users if you choose not to receive messages from them.
