Yes, which is why I’m thinking it would be ideal to add in Pandoc to simplify conversion. We are held back by:
- Discourse Event plugin cannot yet schedule repeat events (weekly meetings).
Yes, just doing everything by hand.
- Mediawiki format template as plain text is collaborated on in etherpad.
- Completed text posted to our mediawiki
- Text also copied over to Pandoc
- Pandoc converts to Markdown
- Markdown pasted to DIscourse with specific category and tags.
Hoping to streamline this process. 
If possible, this would be awesome. Both mediawiki and Discourse and useful tools. It is great to have important information in the wiki, plus discussion in the forum. Obviously, it is ideal to drop url links so people can easily page between both tools.
I know there have been attempts by the wikimedia foundation to integrate both of these tools together. You can find details on the forum. I was also hopeful to allow login to our Discourse from Mediawiki SSO, but that plugin breaks account creation on our forum.
