Hide the sidebar on wordpress.com

Problem

You want to hide the sidebar(s) on your wordpress.com blog.

Solution

Refer to the post Widgets on static pages or single posts by Panos, everything is detailed there.

Lessons learned for me: My current theme (iNove) is a good choice as it supports the possibility to deactivate the sidebar (under Appearance -> Theme Options; this option applies to the blog in general – all dynamic and static pages). Extra for me: the pages without the sidebar become large, I prefer that. There are some themes listed under the link above that have no sidebars but the text is very narrow.

I also posted this question to the forum.
