This is a “quick” how-to guide for using Discourse 27 forum/community software. It contains a majority of the common features avialble to users/content editors, but may not have complete coverage of the featureset. If anyone sees anything to add or correct, feel free to comment. If you’d like to learn more about the Discourse Editor’s syntax take a look at the commonmark 30 (a flavor of markdown) docs for more info.

forum.netzwissen.de läuft mit separaten Containern für Datenbank und Web. Siehe https://meta.discourse.org/t/how-to-move-from-standalone-container-to-separate-web-and-data-containers/29413 Entsprechend gibt es separate *.yml Konfigurationen für den Daten-Container und den Web-Container.

This server reports NOT FOUND, but forum.netzwissen.de reports Discourse 2.5.0.beta4 . This suggests that you have a DNS problem or that an intermediate proxy is to blame. If you are using Cloudflare, or a CDN, it may be improperly configured.

For a robust test, get an address from http://www.mail-tester.com/ Sending mail to REDACTED . . Testing sending to admin@netzwissen.de using mail.netzwissen.de:587. SMTP server connection successful. Sending to admin@netzwissen.de. . . Mail accepted by SMTP server.

If you do not receive the message, check your SPAM folder or test again using a service like http://www.mail-tester.com/.

If the message is not delivered it is not a problem with Discourse.

Check the SMTP server logs to see why it failed to deliver the message.

The output of this program may be available at http://forum.netzwissen.de/ZDAyMGU5MzhkZjcxYjM5.txt You should inspect that file carefully before sharing the URL.

- One CPU and 1GB of memory, with swap, is the minimum for a basic Discourse community. As your community grows you may need more memory or CPU resources.

- [Our Docker container install](https://github.com/discourse/discourse/blob/master/docs/INSTALL.md) is the only one we officially support. It guarantees easy updates, and all recommended optimizations from the Discourse team.

- You should get an email notification when new versions of Discourse are released. To update your instance via our easy one click upgrade process, visit [/admin/upgrade](/admin/upgrade).

Mass invite

1. One user per line.
2. Email is required in the first column, and the email must be valid.
3. Any permissions groups you want this user to be a member of should be in second column. For multiple groups, separate group names with a semicolon group_1;group_2;group_3
4. Normally invited users arrive at the homepage. If you would rather invited users end up on a specific topic, enter that Topic ID in the third column.

name@example.com,group_1;group_2,topic_id
