I'm a web application developer. Unfortunately my design skills are not as "mad" as my coding skills. That's where you come in.
Your friend on Facebook (or Twitter) who is always filling out those "Which Robert Pattinson Character R U?" quizzes.
Or spamming you with Mafia Wars requests so they can earn more mafiabucks, or whatever.
BUT - the appeal of the site has to be broad enough that just about any Twitter user (16 - 40) would not be put off by the presentation. (sadly, this rules out glitter and pink as major design elements of the site)
Also, one element of the homepage should say "Application Developer? Add Your App >>" or similar, as the website needs to both attract end-users and application developers.
*** Contest Addendum ***
* Contest winner will provide cross-browser compliant XHTML and CSS (must look reasonable and resemble original design in IE6, IE7, Firefox 3, Safari 4+ and Google Chrome)
* Contest winner will provide designs for 2-3 additional sub-pages at a later date (again with cross-browser compliant xhml + css)
The winning designer will have submitted the following:
* a logo (as part of the overall design)
* Mockups for 2 pages:
A) The home page
B) The "Application" page
This should include the following:
* The word "Mongoose" prominently displayed in some kind of logo-esque fashion + some kind of image people can associate with the brand
Mockup - Home page
I love really simple designs. The best one I've seen recently is Twitter's new homepage.
Goal of this page: get people to sign up! They do this by clicking on a button that indicates they will be taken to a page where they can login via Twiter.
So on the right hand side, there should be a prominent button saying "Sign up now" or "Login now via Twitter" or something.
On the left hand side, there should be a global activity feed for the site.
Mockup - the Application Page
The place for application content.
