This is a userscript which highlights subsequent posts by the thread-starter in the SpaceBattles and Sufficient Velocity forums. It also displays a short information at the top of each page if a post by the thread-starter can be found on the current page.
QQ upgraded the site in May, and the script hasn't worked since. I don't want to give a rating because I'd have given it 5 stars up until the upgrade, and it still deserves 5 stars for SB and SV.
