MyYahoo home page - number of columns.

Hi, I'm moving from iGoogle to MyYahoo as iGoogle is going to be shut down (god knows why), and I started with 3 columns of information on my home page, I deleted a content block from the home page and I now have only 2 columns available to move my content blocks to. 

Any ideas on how to get this elusive 3rd column back?

I have tried drag and drop, and searching on the web - nothing yet.

Thanks in advance.
