How to move Support System tab?


I used a custom post type plugin that I created on my blog, and the Support System tab covers it up partially and looks somewhat strange. They seem to both be trying to use the same spot in the dashboard and it is rather ugly. On my other user's pages it appears fine, but the general placement bothers me. I would like the Support System to have its own tab at the very bottom of the page, under Settings.

How would I go about changing this? I appreciate your help.
