Bill,
I'm running XP with 512M ram and operating at 2.53G.
I'm inclined to agree with Rick. The sidebar is distracting, and I have no clue what a 'shout' is. Seems we've all been pretty successful at shouting at one time or another. It would seem to narrow the text fields. I don't know how it would effect posting pictures.
Change, from something I've been a part of since 2001, discombobulates me. While you know I appreciate the time, money and effort...the short answer is I liked it like it was before.
EDIT: After posting and going back to the thread, it's way too narrow. I was sorta surprised when the screen popped up, and there was my tiny little narrow post. I vote(for what it's worth) to keep the old.
