Link or screenshots please?

Sorry it took me so long to get back to you. Here's my blog as it is. http://www.wendycockcroftwebdesign.com/blog/blogs/blog2.php

I have customised the Custom theme. I don't seem to have the option to remove the sidebar on *some* pages. It's either all or nothing. WP permits you to change the template for the post or page you're working on so you can have a full-page page.

OK gotcha. You need a more complex skin than the custom skin. Look at the evopress skin. I think it does exactly what you want.

Basically it uses different templates for the "single" view and the "posts" view.

You can duplicate your main.index.php file into single.main.php if you want to remove the sidebar from the single view.

Also check out the manual on skins.

Ah, thank you.
