Can someone explain the rationale behind using "EOM" at the end of a post? I mean, quite obviously it's the end of the post - what's the point??

Obvious you say??? So it's just dumb asses like me that had to do a google search when I first came on here lol...I think the rationale is so that you know that you have seen the whole message without having to open the whole thread....I think....probably way off on that so hopefully someone will provide a second opinion lol

It means there is no message in the text box below, so there is no reason to click on the post to open it. With the new TER, since you can see the entire thread when you click on the OP, it does make less sense to say EOM now, but old habits die hard. In old TER you had to open a post to read it. "EOM" saved people from opening empty posts.

and it is contained within the subject line - an admittedly rare event.

You're right, but I still think it's nice to do for one small reason. I usually check the box to get a PM when my post is replied to. I figure a lot of people do. Admin won't make the URLs to the post within the PMs clickable, so getting to it is a bit of trouble. (I'm not saying it's a huge burden, just more trouble than it needs to be.) If I've seen all there is to see from my inbox, that's nice to know already.

Got it! Thanks for your meaningful explanation. I had no experience with the old TER. Thanks to you and everyone who responded.
