You can always leave a message on their message board. It works a little bit like email, where you drop a message, and then wait for the person to respond at any time they choose to respond. You can't literally have a video chat conversation over WikiAnswers - the message board is the only way to contact a user online.
You don't I'm afraid. WikiAnswers is an open and public information resource, and it is intended to remain such. You can find a member who has answered a similar question to yours in the past and post to their talk page, but even that is viewable by any user on the Internet.
Without specifying an "it", the question cannot be answered.
Maybe he/she don't want to talk about it or avoiding it.
As far as i know you can only talk if you plug in a microphone. I hope that answered your question! 
It is easier to only have registered members edit answered questions because we can talk to the registered users to warn them or to give them tips.
WikiAnswers probbaly said that because there some thing that is not appropiate in the Q: because maybe could have hurt someone. Or not appropiate to talk about.
you answered your own question , it means she doesn't want to be your friend or talk to you
Actually, this is one of the most valid questions on WikiAnswers. Incidentally, it is similar to a question I asked eighth graders twice a year to encourage them to write. For all intents and purposes, it is a blank check. This question could be answered with anything. One could talk about Shakespearean literature, or quantum physics. There are no limits. Short story then, yes, there are endless answers to this question.
www.thetwilightsaga.com :) she gets 1,ooo's of questions hopefully your question is answered.
The "Discuss" button brings you to the discussion page so you can post about the question or answer, and your opinions or thoughts about it. You can talk about how to improve it or what you think about the answer or question.
Sorry, that question can not be for sure answered. We can not talk to animals.
Not yet, but if you would like to have it added, you can talk about reasons to add it in the Discussion Page of this question.
