That was the piece I was missing, now the import is running merrily along. Thanks!
Edit: OK, the import process ran 75 minutes, and the posts are now there. Excellent. It also created users, which I’d wondered about. However, I’m seeing a couple of problems with users:
- It seems that all the Yahoo user names imported correctly (I recognize many of them from my membership in the list), but attached themselves to the wrong messages. They did this consistently–all of the messages that were posted by me now appear as having been posted by the same other user–but nonetheless it’s a significant error that would be a major pain to clean up manually.
- All the imported users are suspended for the next 200 years.
I suspect both of these stem from the lack of valid email addresses in the data downloaded from Yahoo, which is because I’m not a group admin–that’s explicitly stated as the cause for the latter issue, but I don’t know if it would cause the former as well. Thoughts?
If that’s the issue, it gives me something to run down, but also a potential problem–I know there are two living moderators for the group, but the owner died within the past year. Hopefully someone has access to that information…
