DROP Task: Create more thorough documentation for the DROP program

Next week, I'm planning to set aside some time to make a final front-page GHOP status report shortly after the contest finishes. I'd like to at the same time announce formally this program, so that we can help keep our momentum going.

However, in order to do so, we need to make sure that the front page of http://drop.cwgordon.com/ has (much) more there than "Welcome to this site. More to come soon." ;)

Specifically, we need to take the finer points of our discussion at http://groups.drupal.org/node/8321 and break it down into some instructions that mere mortals can understand. Some points to cover:

- What is DROP?
- How does it differ from GHOP?
- How can I participate?
- Who can participate?
- Other?

Marked this as critical, as there are already some people complaining about this due to lack of information: http://drupal.org/node/215331
