There are a wide variety of things to tweak- including adjusting the number of post replies per page that you see, the type of user 'skin' you have, and so on. Near the bottom of the page is a section where you can set the date, time, and calendar settings. One of the settings you can adjust is to enable the small-screen template: made just for mobile or PDA users. For more information, please see this
Adjust the settings to your preferences, then click the Proceed
button at the bottom to save your choices.
