I want to get email notification if a new user registers and if a new post is published.
Some plugin or setting for this?
I can't find any setting for it. Would be relatively easy to do it with a plugin. Just call sendToEmail on the action:post.save hook.
That could end up being a whole lot of emails though!
FYI: I use a plugin so I will get notification when someone registers
I'm not sure you will want to get an email any anyone makes a post.
But you can watch a thread and get an email notification when someone posts there.
That's built in check your user profile settings.. Again, even this can become too much as your forum grows.
