HL2 Retail or Collectors-Cd in Drive

[oldi1knoby]

Multiple Questions:

1. Must you have the CD in the drive if you buy the Retail or Collectors Edition?

2. If you buy the Retail or Collectors edition, will you be able to upgrade to get Day of Defeat? I know with the retail someone's answer was no, but what about the collectors edition? Does it count as a silver account??

I'm sure DOD:S will be available to everyone, the rest of us just might have to pony up a little extra cash for it.
