I was few years user of dozen web sites running under Joomla. Nice feature was an option to install empty or with examples, so that novice could see how it works and how looks changes when a one change data, template... Due to some issue I leaved Joomla and decided to try Drupal 7 but after installation I can't get "that look" with picked theme as I don't have any data for presentation and don't know how and what to put inside administration window. Especially, I'm fan of Omega theme, like GuitarWorld, but don't know how to achieve it. Is there some kind of tutorial for Omega theme, no?
I would like to see some kind of archive with dumped SQL and other files enough to get a picture how it looks when it's lock and loaded. From successful sites it's visible that Drupal is mighty but hard to understand how to achieve all these licks and tricks. Any help is welcome. Thank you.
