About the Southend theme
The theme currently being developed on the web design section of the Drupal SoSLUG site is called, not surprisingly, Southend. (see menu, Networking > Web design).
While this may appear to be part of the SoSLUG site, its actually a separate site, which is being used as a test bed for the ideas and changes members wish to make. At some point these changes will migrate across to the main site. In the meantime, by comparing the two, you can judge for yourselves, whether the changes are positive or not.
