Missing information for Newbies

The wiki and the blog are a wonderful repository of useful information that this newbie spent hours reading. Thanks to all who have contributed. There’s one piece of important information that is at least unclear and that is the identification of the p tab. There’s some info in the wiki alluding to the shapes of the p and k tabs at insertion but to tell the truth I mixed it up for the first two times I used my new device. It wasn’t until I reviewed the specifications for the devices that I realized my error. I would suggest that in info for newbies that it say, the p tab has a red dot. Thanks
