Developing Social [Networking] Site - PHP

have been challenged by a fellow to create a social networking site for our district. Honestly.. I took this up because I honestly think it will help me learn.

Not only will it improve my PHP skills, but also my SQL skills. I am really looking forward to this. My PHP knowledge is low compared to many, but I believe it should be significantly larger by the end of this project.

I hope to have a rough skin done within 2 months.

My plans for the site are as follows:

• Post Board (basic 'thread' where all posts go, giant wall) - September 20th, 2011
• Member Profiles - October 18th, 2011
• Finish basic posts and communication between members - November 10th, 2011
• Allow for more advanced post/profile communications - December 1st, 2011
• Allow for 'Teacher' accounts that will allow teachers to each have their own page, with sections for classwork, homework, presentations, documents, calendar, class schedules, etc - January 15th, 2012
• Present to the school board - February 1st, 2012
• Chat system integration (self-coded) - March 19th, 2012
• March 20th -> Beyond: Re-check all source code. Make improvements where possible. Cut down the source. Continue to elaborate on improvements.
  

That is a rough outline of when I plan to have things done. To some, it may seem like a long while.. but I will probably be doing this by myself (at the start) and in my FREE time. That already cuts it down a bit :)

Anyway, has anyone else tackled something like this? I am looking forward to the adventure ahead :P
