This is a Content Mill. If you don't understand what this implies please read on: If an expert gives you information on a topic, he has his creditability at stake. The articles here are not to show off the wisdom of an expert, but rather to lure you in (as cheaply as possible) so you can click on the ads. This makes money for the website. What you have to understand is that the purpose here is to make money for the website, not to provide you with useful information. As an example, one article was saying to "cut into the drywall" to add a new outlet. What they failed to say was to TURN OFF THE ELECTRICITY first. Otherwise you could get electrocuted! So, please, with any internet article, cross reference the information you read here with other sites.

Ehow offers advice, let the visitor fill out name, email and the question, but when you click to get the answer, they want money for the help and ask for credit card. That is not positive, they should tell the visitor before he fills out all forms, that they will charge for an answer

This site gives confusing, incomplete, mis-termed information, as another poster commented - to get search engine hits. Everyone associated with it is an oxygen-thief and should commit suicide before polluting the internet with more worthless 'noise'. The internet needs to be used for education, not lying. A really simple concept, isn't it? Good luck folks!
