I am looking for some advice on drupal themes. I am coming to Drupal after existing for many years in the phpbb world. In that world, a theme was a complete wallpapered and color-coordinated package. It seems this is not the way things work with Drupal. First of all, it seems, if you want a complete package, you have to pay for it. Otherwise, the "themes" are simply favored layout structures. I mean, I stumbled upon this link: http://hackertarget.com/30-most-popular-drupal-themes-in-top-1m-websites/ that lists the top 30 most popular themes. I learned 2 things from this. First of all, these themes are free (humm...) and secondly, on the drupal web site, there isn't any demo of the themes and it seems to list how great the structure and underlying software is. I am looking for two different themes. Can anyone offer advice. I do not want to pay for a theme: I want an Islamic them;. I want an astronomy / seti theme.
