Yes though I'd like my own ads to be randomized, not fixed, like regular ads would look. I'll take a look at the plugin you mention however so thanks for that.
That plugin is only for google adsense, depending on how your ads work you could embed them as html widgets. Those allow adding html and javascript.
Can it display other ads that aren't adsense? Like if I have my own series of ads I'd like to show on the board.

You can place ads in widget areas.
Widget visibility can be controlled by group in the ACP, place a widget and then select only the guests group if you want to show it to them.
