MyBB Community Forums

I was just wondering if it was possible to auto subscribe all users to posts they reply to or threads they create if so how?

See your PMs.

you can force it on the users via direct sql on the database but you will piss off a lot of your members and they can still edit the setting in their UserCP.

with some edits you can remove that setting, but again, you will irritate your users and subject your site to shutdown due to sending unsolicited email since your users will not be able to opt out.
