The subject is "JnrzLoader 6.1.0.211"? I'll restore it.
I shouldn't have pruned that one, but it's hard to tell if a thread is worthy of keeping without actually reading it, and that takes too long. I do mass pruning... hundreds of threads are deleted all at once, and I usually only look at the subject and the author. If a thread is posted by Patchou, for example, it will absolutely not be deleted. But when there isn't some obvious reason like that to keep it, I usually delete it.
I'm all for the "half-sticky" idea... I've thought about it before, but I'm lazy.
Cookie could be allowed to do the half-sticking...
There should be some kind of indicator that a thread is half-stuck... maybe a little image next to the subject in showthread where the thread rating is.
