Hmm, I tried the code and it didn't change the spacing at all - although the initial spacing was nowhere near as large as what TheWindows7Site posted in his 'before' picture and the spacing is roughly the same as in his 'after' picture so I guess vBulletin fixed it?
That is how it looks - with or without the fix. I was hoping to get the nil space like in 3.8 - possible?
