I run a forum about forex trading in Indonesian language and moving from vb to xenforo a week ago, and love it 
. My member forum also love it too ..
here is my forum link : forum forex indonesia
I have to admit that I`m a novice admin with so little knowledge about programming, styling, and many things that an admin should have ( I guess 
) . so far all I did is using add on and a little change in parameter here and there . The look of the forum it self still standard, not much change from default theme.
After I move to xenforo, my forum content got indexed so fast by google and I guess thats good . I still don`t have a good idea about what I should do with the homepage, so I redirected it to the forum link . Notices system in xenforo is great, I could utilize it to show slider banner ads, or ordinary notices with some parameter.
I`m thingking about using the resources add on from xenforo but having a problem about how to move my forum member attachment to the resource, You guys have any idea ?
