OK, I always hated in forums when people have all kinds of signatures and what-not, so that even when they make a one word post, it takes up 3/4 of the vertical area of your monitor with empty space. I now find that my posts are just like that! I'm one of 'them'!
It appears to have something to do with the stuff in the sidebar by the avatar, but I compare it with other peoples sidebars, and can't pick out any one thing that does it. I suppose I could get rid of my location, club memberships, etc., but like I said others have that in there and there posts aren't so darn tall!
Any ideas? I mean, look at all the empty space under here!
