After your question is typed into the box at the top that says 'enter a question or phrase' and is submitted WikiAnswers will ask what categories you would like to place the question into. After selecting the categories and clicking on okay the question will be placed in those categories.
If you question is moved from a category that you expect it to be residing in or cannot find it there are various options such as going to your own profile page and click on the link 'My Contributions' located to the left of the browser in the blue box and then simply change the 'Filter by' box from 'Action' to 'Questions asked' and hit the 'Go' button just to the right.
There are other ways of tracking questions you have asked such as being notified from the web site to your email or setup RSS feeds to keep an eye on your questions as well.
