Hey,
I think there are a few unnecessary things on this skin which can be remove to make the skin cleaner.
1. When making new threads
User Name:Logged in as ---MAD---
That bit is not necessary.
2. Expand / collapse on categories - Again not necessary as all vbulletin users know the arrows make the categories expand / collapse

.
Thats all for now

. I am sure others will list more below

.
Thanks
MAD
