Overall, I really like the registration thing. And collapsing the threads. And everything else =)

Just one thing - the gray background between alternating threads is a bit annoying. What about less offensive grays? Most of the page is white, so why not take a 90% and an 80% gray?

And what about signature fields? Many of us (not including me) always post a signature (1.8TQMS with Wett and this and that and even other stuff), why not automate it?

Great stuff!

I'll work on a signature field. I implemented it partially, but postponed it to get the forum software released at some point.
