Hi Criag,
I was just wondering if it would be possible to segregate all the questions into groups. We can make a list of very common groups like ADC, DAC, SERIAL I/O, DIO, ELECTRONICS, LOGIC and MISCELLENEOUS. I guess it would be a lot easier for every one to search, answer if this were the case. A person with a Serial I/O doubt would visit that column and probably find the answer.
Regards,
Sriharsha.
