How to log in
To log into this website, first ensure you're not already logged into a Gmail/Google mail account. If you are already logged into a Gmail account, you will be presented with an error and be unable to log in.
Then, click on the OCA logo and use your OCA Email address (e.g. email@example.com) and password, and you will be signed into the site. Once you are logged in with your OCA Email account, you can add your personal Gmail account through the Google interface (if applicable).
If you already have a Gmail account and want to be able to just switch between the two accounts rather than have to log in and out to use this website, follow the details on this Google help page to use multiple Gmail accounts at the same time: How to sign into multiple Gmail accounts at the same time,
