Just about 1% of the internet users are knowledgeable about computers and trouble shooting bugs and errors.
The remaining 99% have no clue to fix bugs and hardware problems.
I definitely belong to the 99% category and as a result, I spend about $60 per year to computer service engineers.
For me and you who are part of the 99% category, there is a web site that offers a lot of computer tips and various educational stuff.
For example, do you want to know how to place a picture into your email signatures? Do you want to know how to re-size a gif image?
There are excellent and easy to understand computer tips at Tips4pc.
