You will need to know your Ogri server username. This will be something like "meredith", not "meredith@ogrimcc.org" as that is your email address.
If you know your password, and it is one that you set, then go straight to:
https://kemble.ogrimcc.org/roundcubemail/
Use your username and password and this will log you into a webmail page where you can send and receive mail.
Please Note that the Ogri webmail page (aka RoundCube mail) is only for testing that all is well, for emergency use if you can't use any other method or if you want to quickly check your mail and you don't have your normal device with you. You should also get it set up on your phone, tablet, pc etc. You will need to use other guides on this site to do so. Please see https://kemble.ogrimcc.org/wiki (you will need your username and password to log in to the wiki site) Please note that not all mail programs have a guide on here yet. If you want to help your fellow members, and you know how to do a program that's missing from here, do please write one.
If you know your password, but it is still the temporary password that you were sent, you will need this next section.
If you have lost, or have yet to set your password, you will be issued with a temporary password on request. When it is confirmed that this has been done go to:
https://kemble.ogrimcc.org/chpw/
This page will take your username, your tmp password and your new password (entered twice for safety), and will then set your password to the one you've chosen. Then you can go to the webmail page:
https://kemble.ogrimcc.org/roundcubemail/
You can call/txt me on my mobile, Facebook message me or grab me at an Ogri function .... or stop me on the street .. has been known ;-)
