Links listed are to external sites and have been chosen because they are helpful. 

"Some information can be out-dated (features might have been moved around), incorrect terms can be used and methods are not always the most direct nor the only way to do something but they still are worth viewing." 

For these reasons, it is best to view several sites covering the same topic. Do you know of a good website to add? Contact me with the address and tell me why. I might add it.
