... or at the very least all the OP's posts?
Just change your settings under Talk: Customise above to highlight the OP's posts in a different colour so they stand out. Then you can scroll through the pages and read all the OP's posts before posting yourself. You can even change how many posts appear on a page in a thread so you don't have to keep going through page after page.
I know some of you see a thread title and nearly wet yourselves in anticipation of posting your opinion before reading barely more than the OP but it might save you some embarrassment when the thread has moved on from say... someone saying her DP complains about her cooking to when it's revealed he's abusing her and the kids. Not to mention it keeps the thread cleaner and more on track.
TIA.
