365 Fitness Challenge
A group of people made a friendly wager that they could exercise 365 days a year for at least a 1/2 hour a day and try to keep everyone honest while doing so. So they needed their own social network website with user profiles and blogging functions to update daily.
Its a private and closed website, but feel free to take a look around at what is possible with a custom wordpress website: http://365orfold.com/
