I would like to have the home page left column set at 300px and change it to 200px for the remaining pages on the site. Is it possible to do this? Thanks!

why not use the left column on the home page and the left inner on all the rest?

So that's what those inner sidebars are for. Sorry about that. Had never used them. Works perfectly for what I'm trying to do. Actually used the sidebars together on the right side, which gives the page a more unique look. Thanks!
