We are currently running Discourse by itself on a domain, where it has been used for forum discussions, since about six months ago.
Now: need to add Wordpress as a front end content server, with tight integration to our existing Discourse forums, with single-sign on for Wordpress and Discourse, the ability to keep a session active when the user moves between the two, etc. And, SSO using Facebook/Google credentials.
We prefer new user registrations for the wordpress/discourse integration to happen through Wordpress, unless you can suggest a better way.
Budget: Flexible. You tell us.
Contact to discuss further so we can get you to work on our project and get you paid fast.
