The Mainframe- Codes
In the Official Site, there are hidden sections that require you to type in a code word. The credits at the end of the movie give away one, but I'll give you 2 more. Please remember, there are tons more codes, you just have to find them out for yourself by typing in your e-mail in the code space.
Codes:
morpheus
That's all I can give, you, you have to receive the rest in e-mail!!!
