In an answer to a question all punctuation marks are possible, but in a question on WikiAnswers the only punctuation that is allowed are apostrophes and question marks.
That only applies to the questions and is a technical limitation.
An interrogative sentence ends with a question mark (?). This punctuation is used to indicate that a question is being asked.
WikiAnswers uses all three, but "ok" (the third example) is an example of poor punctuation, so the other two are preferred.
WikiAnswers wishes for you to use commas and proper punctuation in your answers, but only question marks and a few other symbols are allowed in asking questions. The use of periods and hyphens are sometimes allowed, as well as other specialized characters such as the degree ° symbol.
You have tried to use punctuation other than a hyphen or question mark. After a question is asked you may add a hyphen, period, or apostrophe. If you are asking math question, use words instead of punctuation - (ex. add instead of + , subtract or minus instead - , multiply instead of * ).
No, on WikiAnswers, we do not speak to each other.
On the English site, English words that address the topic and focus of the question. For any other the other WikiAnswers language sites, the language of that site is best. See the related question below.

It's possible that there would have been another WikiAnswers. There are now many wikis, and many question and answer websites. However, there is no other major question and answer wiki. There was one that started in 2006 called answerwiki but it didn't go very far.
Since WikiAnswers is a Wiki, the authors of WikiAnswers are the community. Users from all over the globe contribute questions, answers, and other necessary clean-up to WikiAnswers whether registered or anonymous. In other words, there are millions of editors and authors on WikiAnswers who contribute daily. There is no single editor or author of the questions and answers on WikiAnswers; you could say that WikiAnswers is "authored" by its community of visitors. As WikiAnswers contributors, we ask and answer each other's questions. The contributors of an answer to a question can be found on the question page, which lists the most recent answerer only. For a complete listing of all those who contributed to an answer, view the "Question history" for any Q&A located on the toolbar to the left of the question under "Question tools."
WikiAnswers, like any other question website, is free for anyone to contribute to, and so of course cannot guarantee the accuracy of every answer. However, the answers on WikiAnswers are free for anyone to look at and they have helped many times.
