The only thing I would change....and I know you can change it because another vB I'm on is updating software....is the line of options for each post...
email/www/quote/edit.....you have this on the bottom of the persons reply....I would put in on the top just to the right of their name.
What happens is when you look at a persons information on the left...you look right and see the quote/email/edit line and associate it with that person...when in actuality that line is for the person who made the post...is this making any sense??
Check out this link....its from the DVDtalk.com website and they are changing to this software as we speak...I'm doing some beta testing.
