you can remove or add anything you want in your sp theme… first, make sure you have your own theme vs editing one of ours to keep from losing changes on upgrades… http://codex.simple-press.com/codex/themes/theme-basics/creating-a-theme/

in this case, edit the template file spFoot.php and just remove the sections that do the stats and acknowledgements…
