Couple items that I find annoying (one of which Fyron already mentioned):
1. Horizontal sizing seems off on the tables. Using Moz 1.7.2 at 1024x768 and about 25% of the right side of Posts are 'offscreen' ... e.g. have to slide the horizontal bar right.
2. Date format. You got rid of DDMMMYY. Pet peeve
3. Reply method: I don't like the new threaded model. Like the flat single topic model much better. While the view is optional, replying isn't. To reply to the main topic, you have to hit 'reply' on the first post. If you hit reply on a later reply (say the Last post in the current thread), it ends up threaded. Would prefer a flat thread. New system seems like a step backwards to the pre-UBB cgi Boards of the early / mid 90's.
Other than that, no issues. Most sites do posting ordering similiar to this so non issue. Never was one for skinning so indifferent about this also. Out of curiosity (maybe I missed the thread) did Shrapnel ever post why they were moving from UBB to UBB Threaded as opposed to just updating UBB or $insert_some_other_BB_here ... was this hardware / cost / or scaling driven?
