Ok - here's the scoop.
We are getting a lot of requests for custom backgrounds for the 2 calendars.
If you want to create a custom one that will look good on your site you can.
Contact graphics@gonnahappen.com and we'll send you the specs or files to work on etc..
Since it is Free there are some stipulations.
Also - once you create it and send it to us it will then be public domain for others to use.
But what the heck - make something that blends in with your site and we'll help you get it installed.
