I was surprised that when I had to log in that it said I had attempted to log in too many times so it seems our site had some sort of bot login issues hence the validation part, they are always trying. My reason for this post is to comment that I do like the idea of the videos on the different classes and would not mind seeing other classes covered that are a little more involved like the connector ends since there are so many different ends and it would be nice to have a more concise understanding of what is allowed. The ones that I wonder about are the usb connectors, the sata and sas connectors from the cables and motherboard connectors that look to be gold or bright brass but are hard to tell the difference. Of course the difference between low and high peripheral boards does throw me off a little and when in doubt I tend to throw most in low peripheral box but I may be losing money in the process. A video may give a better understanding of each class.
