1. The portfolio is comically large. Were there a bunch of senior citizen complaints about the old version?
The "Today's Change" column alone is nearly twice as wide as it needs to be. And does anybody really need to know the percentage change to 2 decimal places? Personally, I preferred the old portfolio, where you could see most of it without having to scroll down forever.
2. What happened to market lab? 
3. On the calendar page, clicked-on links don't change color, making it harder to remember what you've already looked at. If you're going to make the fonts huge to help our aging eyes...then help our brains also! 
4. On the forum page - having to click on each message to read the full post is annoying. Also, the "Previous | Next" links should be at the bottom, not the top. I'm assuming most people read from the top down...
Otherwise... nice job!
