Port of theme to Drupal 7, thanks go to Zarevac for doing the bulk of the work.
Other things to note:
"content top" and "content bottom" regions have been removed as they were working around a problem that no longer exists - in Drupal 7, the content region contains the main page content, so you can order the items however you wish with no need for a separate "content top" and "content bottom" regions.
Please test and report problems
A new release of the Module - it adds a secondary sidebar (disabled by default and pretty ugly AFAIK, but something for people to work with)
The main horizontal menu can now be replaced by placing a menu block in the correct region.
BEWARE - Some region names have been changed, so when updating a live site you WILL need to move the blocks into the correct regions and if this was previously done programatically, you may also need to update some code.
The Sidebar has been Renamed to Sidebar Primary, the three footer regions have been renamed too.
New development to add a third column to the arthemia theme. Beware that some region names have been changed, so updating may require you to move the blocks to their correct regions again (however, so far they should fall into the correct region automatically).
This is still a work in progress and dimensions, padding and margins etc may all change with little notice.
If you think this theme requires anything or can think of something that will make this theme better, please go ahead and open a new issue for it.
