3rd edition

Dear TGMers,

Have heard about the changes/removals (not really sure) on the 3rd edition. If any, what are they? And why? Can you point me to a link that discussed this already.

I've heard that some prefers the 3rd edition than the later ones. Don't see any explanation though...some say its got to do with accum #3, which I am very interested in by a LOOOOOT.

Anyone who could shed the light?

All the best,
SVSV
