When you post a question - the computer system 'reads' the words and places the question into up to three categories depending on the wording. For example, your question has automatically been posted in the 'Questions about WikiAnswers' section because you used 'WikiAnswers' in the text.
no, I answered this and I'm not part of it
As far as i can tell, just you.
It is wrong to post bad taste jokes anywhere.
Wikianswers is a public community. Anyone can ask questions and anyone can answer them. If you have any question you can post it in wikianswers and someone who knows the answer to your question would respond.
you have to sign up with face book
Yes, you can. Post them and the WikiAnswers Contributors will try to find answers.
There is no specific 'Jokes Category' on WikiAnswers. But there are two categories called the 'Humor and Amusemet Corner' and 'The Most Amusing Questions Ever Asked On WikiAnswers' where you can post cheesy questions or silly, but not inappropriate questions. (See related links for a link to the categories)
WikiAnswers is not a textbook cheating website. We do not post textbook question-and-answer pages at all.
Some people apparently post fatuous questions on the algebra section of WikiAnswers!
You can, but questions like that would be better suited for a Q&A site that allows people to post separate answers to questions, such as Yahoo Answers, Quora, or Aardvark. Questions on WikiAnswers can ask for opinions though. When questions do ask for opinions, people can post their separate opinions in separate paragraphs, or separate the answers using bullet points.
WikiAnswers does not provide answer keys for educational programs. Do not request or post these answer sheets. You may ask one or more questions of a related nature, but do not copy these questions and answers into WikiAnswers.
So they can post stupid questions like this on Wikianswers
