I'm experienced with CSS but just beginning on wordpress.com--and trying to figure out how to work with the Sandbox theme. I did pay for the Edit CSS upgrade. Much of the information I've found dates from 2007 and 2008 and does not seem to apply to the current version of Sandbox (1.6.1) as it appears on wordpress.com. For example, it isn't possible to select a "skin" on the Manage Themes page as many posters advise. Can anyone point me to updated instructions on modifying 1.6.1? I'd like to create a 3-column layout.
The blog I need help with is janspiller.wordpress.com.
