CMS Made Simple Forums

I've tried every variation of css (that I know) to move the dropdown ul over to the right so it falls directly under the nav ul (main - ul Home, etc). Currently when you hover over the main nav ul li the dropdown displays off to the left and not directly under the nav. I cannot get it to move over to the right and fall directly under the main nav ul li.

Any suggestions?

If anyone needs the url to check it out great, I can pm that to you.

Most likely we will need the URL to be of any help...
