Tip on Customized Pages

Don't make customized pages just to hide a block.  If all you need is to omit or hide a block, use the "Show block on specific pages" feature found at the bottom of every block in the administration pages.  You can include or exclude any page or number of pages (using the wildcard *).

It works best especially if your theme is fluid and you want to take out an entire region by hiding the blocks.
