If you’re used to the mailing list-style way of reading this, you can set Discourse up to act in a similar way by doing the following:
Go to settings by clicking on your avatar in the top-right corner then clicking on the gear () icon
From the settings page, click on “Email” on the left side
On the email settings you can configure notifications & digest mails, but there is also a checkbox at the bottom of the page for “mailing list mode” - checking that should make you receive posts as emails in the same manner as the previous mailing list
To create a post via email, you can send an email to swiprolog@discoursemail.com. This will create a new topic in the “uncategorized” category.
I’ve set it up now so mail to swiprolog@discoursemail.com will create uncategorized posts; I can also make some aliases for creating posts in specific categories if desired.
