Good work Kiriakos-GR. A guy asked for help recently, and you seemed to think his questions were not worthy of a answer.
You should thanks the people who did those videos ...
There is some things , that you can not learn in forums , there is no quick answers for them.
And there is also times, that the text on the board by it self , it does not help , no matter how much it will be used .
That's why I had reacted that way.
One well made video , its an more effective way so to distribute knowledge over complex subjects .
