10. Final Production
Yeah baby! This is the final "Look, see? It works!" You'll clean up the code from the Working Production, sharpen up design elements, turn JPEGs into GIFs and vice versa, and ensure that your final output is as standards-compliant as possible. You'll also write a list of the current weaknesses in the system which need to be addressed before you can release the system: things like removing useless code, ensuring there are no server memory leaks, etc.

11. Testing & Final Approval
The word of the day is "hammer". Get tonnes of people to use your site and make sure they enjoy it. Take their comments into consideration, but unless they are extreme, don't rush out and do a redesign -- just tweak the site where necessary. This is also the stage in which you nail down your final codebase, make the code modular so you can reuse it later, and give each other bruises from too much patting on the back.
