When you add to your site the parameter "?tp=1", you will see all modules positions for this page, and you will can move modules which you wish to positions which you have.
Please check:
www.mgmideasinmobiliarias.com/?tp=1
and
mgm.vitsis.com/?tp=1
These sites have different templates, so modules positions grid for these sites look different. It special created so.
If you need rearrange modules (not depend of current positions ) You may use our CCK component
