Hi

Recently a new friend of mine asked about having sidebar on single posts on WordPress theme TwentyEleven.
This is my theme edit/customisation for this. Please check it out on my demo page @
onlinewpthemetest.richard-dickinson.com

Edit details:
Add to single.php & page.php (just above get_footer code)
Comment out body class function in functions template (functions.php)

I wonder if WordPress will include the ability to have a sidebar in future versions of TwentyEleven?
It seems many people would like this feature. We will have to ask WordPress.org & see if they will!

I will leave this theme here for a little while as a demo-enjoy!
