You have this toward the bottom of your page:
<input name="ScrollTop" type="hidden" id="ScrollTop" />
<input name="__dnnVariable" type="hidden" id="__dnnVariable" value="`{`dshReset_imgIcon:exp`:`-1`,`dshQuestionAnswer_imgIcon:exp`:`-1`,`__scdoff`:`1`,`__dnn_pageload`:`__dnn_SetInitialFocus(\u0027dnn_ctr618_Login_Login_DNN_txtUsername\u0027);`}" />
It looks to me like DotNetNuke adds this so that, if there is a Login module on the page that the "focus" is sent there. Presumable this is so that people will be able to login easily.
I would probably mode this to the top of the right hand column and also set permissions so that it is visible only to unauthenticated users. That way, only those who haven't logged in will see it.
Your skin also has a "login" link in the footer. One of these is redundant. If most people will not be required to login, I'd remove the Login module from the page and let DotNetNuke and the Login link handle this for the people who can login.
