Home - This is a page that will have a login/signup section at the top (header), the main area will have a image (something appealing communicating "surpass yourself") and bellow that the main area will have the hotest/top rated challenges that are being funded with a fund status (70% of fund goal completed) and finally a footer section with the copyright notice and a link to the terms/privacy.
Create Challenge - This will be a form with several steps so I will list them bellow (this should work with tabs/breadcrumb navigation):
1- Select if your are going to challenge yourself of a friend;
2- Select a "pre-made" challenge (category, this way some field will be pre-filled) or create a new custom challenge;
3- Challenge information such as url, name, description, motivation, url for video/images about it, criteria to complete (likes/money and how much), due date to complete the challenge, hashtags for the challenge and if you have some "early funders" please insert their facebook name or e-mail
Challenge Detail - This is the page where people will be able to see a challenge info and fund/approve it. The challenger will be able to see how much has already been funded to complete the challenge. There is a great highlight to the provided media and the challenge motivation here. The "news" tab is a like a timeline of actions in the challenge (if it required more than one image to prove i.e. losing weight).
Please check the attached wireframe for each page for further detail.
