After several people edit or extend postings on our sites ( 1k words typical )there may be several dozen copies many of them days or weeks old.
Now that we know that every one of these old versions is stored in the database we understand why it is growing exponentially in size making it all but impossible to manage, download, upload etc. While having all these copies is somewhat helpful during editing, once an article is published they are of little or no further use. Some or all need to be deleted for very practical reasons.
We find no way to delete the unwanted copies or to limit how many are created and stored. We'll need a work around or a way to turn off the auto save functions. Even a limit number that discards earlier versions might be helpful.
