Trying to answer my own post, any acknowledgements will be helpful.
In order to set the mailing list behavior consistent for all users of the site consistently:
- I could edit the User Setting in DB for all users.
And to selectively set the Watching, Tracking Categories Consistent for all Users.
- I could set category tracking level defaults historically
I plan to do that after taking a backup of my instance.
Is my thinking along the right lines? Am I missing anything?
