Does it work with a WordPress multisite configuration?

All of the plugin’s functionality except for using Discourse as the DiscourseConnect provider for WordPress works with multisite configurations.

Does this plugin install Discourse for me?

No this plugin acts as an interface between Discourse and WordPress. For it to work you will need to first set up
Discourse forum. You can install Discourse for yourself following either of these guides:

• Install Discourse in Under 30 Minutes
• How to use the Discourse One-Click Application on DigitalOcean

Can I import old WordPress comments as Discourse comments (i.e. “replies”)?

No.

Do WordPress and Discourse have to be installed on the same server?

The plugin uses the Discourse API, so your forum and blog can be hosted separately and the integration will still work.
In fact, we strongly recommend hosting the two applications separately, since their hosting requirements are very different.

Is it possible to customize the comment templates?

Yes, the html templates used for publishing posts on Discourse and for displaying comments on WordPress can be customized in your theme.
This is done by hooking into the filters that are applied to each template.

For more details on template customization, take a look at the Template Customization topic
on the Discourse Meta forum.

Can my Discourse theme inherit the styling of my WordPress theme?

Not automatically. You need to apply custom HTML&CSS to Discourse in order to match the theme of your WordPress site.
