And let's see where it goes using the "real" posting page....
EDIT: It goes to the top of the page, you're quite right.
That's annoying. I want it to go to my post every time I post - back to where I was. I view many more posts per page than the default so it can be a looong ways up to the top.
It's not a huge deal, though.
I know some forums have the feature that pops up:
"While you were posting, someone else posted, do you want to view the updated thread?" or something like that. That's a neat feature, too, but not a huge deal
