Two things about this: 1. In the old site, "Founder" wasn't anything special, just a record of the guy who created the group. He didn't have to be an admin, though. In the new site, "Founder" is a security level - an admin that can additionally make new admins and also can't be kicked out of the group. 2. Existing groups imported into the "Founder" role the oldest-joined member who also was in the system's full control role. There were a few fallback options, too. But the point is that the guy you saw listed as "The Founder" in the old group system's homepage wasn't checked, because it was just stored as a string, not an actual reference to a user, nor did that user necessarily have any powers in the group anymore. Indeed, he might have been deleted. If you still think there is a problem with your group, please let us know, we still have the old data. But I'm reasonably certain the imports mentioned here are correct.
