[development] Passing options to the front page via the URL (was Passing options to the front page)

[Jeff Greenberg]

Decided to finesse the problem description. Let's say I have a function 
that will change the data shown on the front page based on a parameter. 
The parameter should be provided via the url, so that it can be 
bookmarked, entered directly into the browser by the user, or selected 
from a link. How can that be done?
