After the migration to Patheos, I learned that it may, in fact, be possible to migrate our old Discus comments over to Patheos from the old site. In order to avoid a lot of problems caused by publishing comments on the new site using the Patheos system and then switching back to Discus, all new comments are being held up in moderation while we wait to get the Discus comments migrated. If the Discus migration works, we will notify each comment author individually asking them to repost their comments through Discus. If the Discus migration does not work, we will “approve” each of the pending comments through the Patheos commenting system.
Thanks for your patience. I apologize for the delay!
