When the web started to gain popularity in the mid ’90s my friends asked me to find the best web content in topics they were searching because they knew I had a trick for finding it. I soon knew how I was going to help people find the content that they were looking for and decided it was going to be something I knew about, IT and computer training and tutorials. I have a Computer Science B.S. degree and I’ve been a computer consultant for the last 20 years. Yours, Albert Where may this letter come from It comes from ______ about computer.
