When you change a sites look, do you let the members preview it first, or just spring it on them?
 

for those of you who have regular members, if you change the look of your site do you give a sample of what the site will look like first to let them get a taste of it?
Or do you just change the look and they will deal with it?

Why not have a button/link to change the layout to the new one?
I take it you seperate code and presentation layers....
