I wouldn't waste my time with a plugin. Just go into your admin panel, then to Templates & Styles -> Templates -> your currently active template. Then, find a template where you'd like to place an ad, such as: Header Templates -> header Then add your google adsense code, surrounded by a div, like this: <div align="center" style="padding: 10px;"> <script type="text/javascript"><!-- google_ad_client = "xxxxxxxxxxxxxx"; /* Forum 728x90 */ google_ad_slot = "xxxxxxxxxxxx"; google_ad_width = 728; google_ad_height = 90; //--> </script> <script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script> </div> Code (markup): If you really want to get fancy, you can install the mybb php template conditionals plugin, then use code like this <if $mybb->user['usergroup'] == '4' then> <div align="center" style="padding: 10px;"> <script type="text/javascript"><!-- google_ad_client = "xxxxxx"; /* Forum 728x90 */ google_ad_slot = "xxxxxxxxx"; google_ad_width = 728; google_ad_height = 90; //--> </script> <script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script> </div> </if> Code (markup): that extra if statement means that the code will only be shown to guests - your members won't have to see see the ads. You can also install this code in your footer, as well as other templates.
