I'm definitely looking forward to the redesign. I was counting the days awhile ago, then let it be, now it's popped back into my mind with only a few days to go, awesome.
Things the redesign really needs:
1.) A way to edit posts. Specifically when commenting on people's pages, forums as well would be awesome.
2.) Separation of Games and Movies. Sounds like you already have this in mind, and from our emails in the past, I'm sure this will be done correctly. Hopefully this not only includes navigation, but daily awards as well.
3.) Emphasis on the Audio Portal. I've recently submitted my first music to Newgrounds, and it all got buried, despite high ratings. If you're not in the top 20 or so, you aren't getting views, which is sad. Something needs to be done about this. More tags, more specific genre listing, better search features for finding audio, etc.
4.) Use the space available, screw people with old ass computers, they can learn to scroll a bit, or upgrade they're ancient monitors.
5.) Add better notification for communication on the site. When I respond to someone on my page, I want them to know, they shouldn't have to come back to my page, check that news article a few days later, and see if I responded. For instance, you (Tom) commented on my latest post, I responded, conversation dead because you probably won't check back. You should be notified I responded, it'll keep things more lively between members.
All in all, I look forward to the update. If these things aren't in it, work them in as time passes, but I know the above is good for everything, by everyone ;)
