How do you display the name of the logged in user who submits the alert about the post in the alert email? I've already tried :
[AS:PROFILE:DISPLAYNAME]
[CURRENTUSERID]
[AF:PROFILE:DISPLAYNAME]

and none of these work.

I am not sure this is possible. I believe any reference to a user would be for the post author, not the post Alerter.

Can the email or username of the alerter be shown in the email so?

Thanks Ben. But surely there's a way to track or trace the person who alerts / reports a post.

I asked for this a couple of years ago. It's not possible right now.. Which is really frustrating..
