Hi,

I am a beginning at blog building. I saw many blogs using the Atahualpa template but with 2 columns instead of 3. I went through all the settings, but I cannot find where I can change that.

Thanks

Read the documentation on the sytle sidebars option section

Ok, so where do I find this documentation?

I checked: http://wordpress.bytesforall.com/ and didn't find any, but the forum link.

Thanks
Philippe

The documentation is part of the theme options, so go to the ATO->Style & configure SIDEBARS options and read the on screen documentation
