another thing about prosilver is that it is a Foundation for many other styles which could be called "appealing"
Many 3.2 styles on offer - depend on prosilver for inheritance.
You wouldn't know it half the time looking at the alternative style but that alternative style wouldn't function without prosilver being at the top.
there are over 20 styles, probably more in the Styles database
that 3.2 Admins can Install, a lot of them look entirely different to prosilver
