Thanks for explaining all this. Really it sounds like you need to ask the projects you are contributing to that are using Discourse to work on this. Right now it’s not even clear to me how many projects are making use of Discourse Code Review and how it’s working out for them. Feel free to PM me with some details so we can get specific.
That plugin is different.. the discussions live only in Discourse and are embedded at the bottom of WordPress posts. They are not synced.
