Very cool, Chen!
I'm planning to install it with a small variation: as I don't like that textbox at the end of the thread, I'll put a button or a link near the existing [Post Reply], something like [Quick Reply], and will open a javascript page with the textbox as you proposed.
What do you think about ?
Thanks a lot for sharing your work.
P.S.: what about closed threads ? Are they managed ?
Thnx
