PTSR
Acronym for Posting To See Replies. Started by an unknown person on World of Warcraft forum. The forum is bugged in such a way you often have to post something to see other replies in a thread.
You can see before opening a topic that there is i.e. 8 replies in this particular thread, but whe opening and reading, you may only see 3. You then have to post a reply yourself to be able to see the last 5 replies. People then often type only 'PTSR' just to let everyone know that they didn't have anything to add to the discussion, they just wanted to read what others had replied.
