Why do you want to close the post but not remove it? There’s no reason to close it. This thread may help users who find it in the future. Just because a problem’s solved doesn’t mean that the thread needs to be closed. I’m pretty sure that thread closing is only needed when a thread is frequently spammed or discussion is derailed.

To be nice to Sannse. A technical reason too - say Mime is trawling message walls. He will have to restore my thread and then delete it as there is no preview. (I've done it before.)

There's lots of instances in which someone might need to restore all threads, like if other users try to harass a target and then remove the evidence, or if I did the same.
