In YahooGroups (web interface), the URL of each message ends with the number of that message, and that number is incremental starting with "1" back at the beginning of the group and its first post.
In Groups.io, the upper right corner of the web interface says "1 - 20 of 13074"
That is where I am getting my numbers from.
Over the 20 years my group has been in existence, it's possible some messages have been deleted.? But 133 seems high.? I am the only one allowed to post, and I am the only owner/moderator.? If any had been deleted, I'd guess less than a dozen, not over 100!
Is there a way to export Groups.io messages in mbox format so I could 'diff' it against the YahooGroups mbox export and identify the oddities that way?
