They're not really the "skin", they are just some of the vBulletin options that I have chosen not to use as I don't think they add anything significantly useful. Quick reply is a particular case in point.
Tell me more about the other things you mentioned. Which tools are you referring to? What do you mean by "Advanced view"? Do you mean Threaded display mode? If so, I have yet to see a forum where it works well.
There are lots of bells and whistles on the current Vbulletin release, but I have made a definite effort to keep things simple. Despite this I still get emails from people who need help finding their way round . . .
Despite Codprawn's protestations I am always open to suggestions, but I might take quite a lot of persuading.
