Anyone (including you) can answer (or edit) questions. This is a "wiki" site that is open to everyone. There are also experts and supervisors in each category who provide as many detailed answers as they can and also supervise the other answers for quality.

If you want to remove every answer that you wrote and do not want your user name (or ID) to appear as the one who made the last edit to an answer to a question, ask a supervisor to get rid of your answers for you. The supervisor will only get rid of your answers if they are invalid as an answer to the question, and will not get rid of the answer if it is a good answer.
On the site Home page, click the blue word "Directory" on the left. At the bottom of the page that will then pop up, click the word "Experts."
For a better solution, I recommend contacting the experts/professionals available in your area. Much preferable if they are experts in Squirrel removal. If you live in Ontario, Canada, Contact the Critter Guy team. They are the best services I’ve experienced.
All of our answers are given by people from all over the world. Some answers are shared by people with general knowledge, students, some by people who have hobbies in the areas surrounding your question and others are answered by experts.
Answers dot com is not a download. So there is nothing to get rid of except the temporary browser file on your computer (see history or Browser Temp Files). These only re-occur if you re-visit the site. We hope you do come back.
