Customize User Registration Form

I'll customize it by removing all the fields on it...

Srsly, what do you need done to this reg form? It's pretty hard to email you a quote for doing some work when the work could be between 2 and 80 hours. Yes, that's right. Some registration systems, like the one on fastcompany.com, take upwards of three weeks for two developers to build & theme. That's 240 billable hours at $120 an hour, which will cost you over $28,000 for a user registration system.

Or it could be as simple as adding another field to the form asking for a person's age.

Well, what is it?
