LiveMail (also applies to browser) 

Win7

I often "Add" words to my LiveMail account, but there have been times I'd like to delete an added item.

For example, I might "Add" LiveMail above, by right-clicking on it and selecting "Add". Suppose later I decided that LiveMail was an error, and I should be using "Live Mail".  I'd like to be alerted when I use LiveMail.

Can this be done? Is there a way to edit the dictionary? I did try "Open spelling dialog", but that didn't seem to apply.
