PocketT is a free (GNU GPL) Drupal 7 theme originally created by Nyssa Brown Design and ported to Drupal 7 by CrashTest_. Its sole purpose is to be compact and focus on blogging, while still maintaining an interesting yet simple design.
I have added a sidebar for those who need it. The original had no sidebars, however I believe we need someplace to put the login box, and navigation menu. You can leave the sidebar empty and it will not show up, and you will be left with the original clean single column design.
It is standards compliant, and has been tested successfully in IE6 and FF3. Please let me know if you find any inconsistencies in other browsers, and I will address them at that point.
