Hi Dubravko,
Agreed, there are many newbies questions around lately; in fact too many.
The topic of "how to ask technical questions" is as old as the first internet forums.
Somehow I doubt that another document stating "put in information x,y,z when you've got questions about a, b, c" will improve anything here.
I guess it boils down to the ability and effort of the asking person to communicate their problem properly.
Concerning the basic/simple/newbie questions the SCN position on this is clear and straight forward: we don't want to discuss them here.
Check The SCN Rules of Engagement on that. It's a platform for professionals, that is, folks that make their living of dealing with SAP solutions.
We do expect those professionals do their share of self-education before they ask for other people's time and attention to their issues.
In my opinion that's a fair point and by using this community everybody accepted this.
Part of that is not to answer those basic questions but to "abuse" them, that is: click the "Alert Moderator" link and put it "Failed to search" for reason.
Replying to floods of newbie/lazy search questions is only adding to the waste in the communities.
Having an FAQ is a great idea and there's nothing stopping you from starting one.
All you got to do is to create a document or a WIKI page and off you go...
There are plenty of FAQ documents available already on SCN in case you want to have something for orientation.
Looking forward to your FAQ! 
Cheers, Lars
