Category:Unanswerable at present

From Wikianswers

This category is for questions which might be conceivably answered, but which are not possible to answer at present. For example, Is there life on other planets?

If the question is really an idea for something that might give others an idea to implement it (e.g., "Is there an extension for Firefox that does this..."), you can also (or instead) leave the idea at the wiki, AllYourIdeas (a wiki which is, as with Wiki Answers, under the GNU FDL).
