Not sure this is a real bug, but

When you're in advanced mode creating a thread and select Subscribe to thread check box.
It defaults to updating every "Week", not when posts are updated regularly.

Clicking subscribe anywhere else changes it "None".

Just pointing it out in case it can be modified, so that thread updates are not overlooked when you subscribe like at the top of the post. I don't want to find out in a week, I'd rather know straight away.

Not complaining and since I know about it, I'm fine.
Just throwing it out here.

I randomly get subbed when I make two posts which get merged. This happens sometimes.

Yeah I get this too but it goes away after refreshing page or going to forum homepage
