thanks yuo all for your answers ..I have a clear idea now.
but the major thing worry me about C2 is the lack of tutorials and manuals to learn..
dont get e wrong... C2 tutorials are good and well done , but there arent so many to help complete newbies to learn deepest in the tool.. I know there are tutorials for almost every aspect of C2 but I need books to learn gradually...
MMF2 for examples has tons of step-by-step examples and so many books to learn , due to the age of the engine ,I know, but this help so much new developers like me..
I'm very undecided , I'm afrad to make a wrong choose and waste my money and above all my time if I'll make a wrong decision and after I'll must restart ...again...
