Depending on your situation, the easiest thing to do would be to not use SSO to log users into Discourse. Then you could just export a list of users from WordPress, extract their email addresses into a CSV file, and use the Discourse bulk invite functionality to invite them to your forum. You could customize the invite email to let users know that they need to click the link in the email and agree to join the community. Once they’ve done that, they are free to interact with it by email.
