I would, however, join others in recommending that the default layout be changed back to avatars on the left. While Zippy has a point (people do typically react negatively to change), I believe that this particular change is undesired not only because it's different, but because it disrupts the natural flow of your eye as you read posts. Typically, as I enter a new post I want to know who is "speaking". To do that, I would have to look to the right to see the user's name or avatar, then look back left to begin reading their post. I'm sure that given time, I would adjust to this unusual layout, but why should I have to do so?
For those users who it bothers, you can change your theme to subSilver2 to fix it, but I believe that this will negatively impact first-time users to the forum or individuals who are unaware that they can make this change to their preferences.
Also, I second (third? fourth?) bringing back the quick reply box, as that was a nice time-saver when available.
Finally, I have one more suggestion that others might not agree with, but... can you disable the signature feature please? It's just that I don't want to have to waste time re-reading the same moronic line that certain users (*coughpinkysasscough*) are liable to come up with, or worse, be subject to numerous flashing images in every post. I believe there was a discussion about this when we first made the forum move to php, and the general consent seemed to be to leave them off. It frankly concerns me that it's now an available feature, and IMHO it would be best to get rid of it now before people get used to having them.

P.S. Quotes and smileys are working now.
