That's quite an important note...
You need the computers to progress and the reports add to the story.
It's also a good idea to write down all the codes and stuff that you need, as it's a real pain in the arse to keep having to go back and check them when you forget...

Login Ryan
List
List News (whatever directory)
Read Headlines (whatever file)
Sometimes, you'll have to login as different people, on certain consoles, but the commands are always the same.
