There is a saying like "Knowledge is the power". In the last 4-5 years i have seen lot of people trying to start an online business without having a clue about basic things. Guess what.. sooner or later they failed. You can't just make money online if you don't have any kind of technical/marketing knowledge. That preatty much apply to any kind of online business: affiiate marketing, PPC, blogging, etc.
Here is something that can help you though:
http://www.imvideocenter.com/wordpress-marketing-video-tutorials/. This is pretty good lifetime memberhip site. For a decent price you get access to 30+ video tutorials, starting with basic things like register domain, select host, change DNS (is this already greek for you?!) and getting through all steps of installing and working with wordpress. The tutorials also comes with PDF transcript, so you can read the same info presented in the videos. If you are a complete newbie (or just a newbie

) interested in blogging, it may help you get off the ground.
