I see that you are looking for online computer training courses. Well, there are many, some free and some offered by the gurus, and the professional ones provided at Wealthy Affiliate University.
Often the gurus give such online computer training courses away IF you will give them your name and email address. Then they can pester you to death with information and offers. They can milk you until you are broke. They do not always give what you really need to succeed in this business.
If you go to my site you will find free tutorials and other information on many Internet marketing subjects. You will not be pestered by email as I don't require it or need it.
Like I say, the best online computer training courses are found at WAU. I have been a member for almost three years. There is a monthly fee, but I save money by paying on an annual basis, by getting free hosting, and by introducing marketers to the WAU site. Actually, like many WA members, we end up getting WA free.
I hope that this has been successful in your search for online computer training courses.
