The forum is getting clogged up with threads about the 64 bitness of SL and associated applications. Common questions that are getting asked, in many cases, several times a day; 1. I don't understand 64 bit. 2. Why isn't my Mac booting a 64 bit kernel. 3. How do I boot a 64 bit kernel under Snow Leopard. 4. Why aren't all my applications 64 bit. 5. How come my Mac crashes when running the 64 bit kernel. Etc. It might be helpful to have a nice FAQ created by the community that is stickied in this forum at least for the next few months as many users ask these questions over and over again.
