First, just try being nice to other contributors. Try complimenting them on their contributions, but only if they are good contributions. Start off on the right foot by introducing yourself, and correct spelling, grammar, and courtesy is essential when writing on another user's message board.
You cannot send friend requests on WikiAnswers. WikiAnswers is a question and answer site, and was not meant to be a social networking site.
Not on WikiAnswers
No, friend requests on WikiAnswers cannot be sent. Generally, people use the search feature in the top right to find members, and keep in contact with them from there.
Yesss
WikiAnswers is a site of questions and answers on a wide variety of subjects; it is not, however, a dating-style site.
WikiAnswers is designed for asking and answering questions, not for social networking/making friends. You can chat with other contributors on their message boards and see if they have a Facebook account attached to their WikiAnswers Profile. If both of you have a Facebook account, then you can ask to be their Facebook friend.
WikiAnswers cannot predict your future.
Right now WikiAnswers does not have a "Friend" button. Therefore you can not do this.
WikiAnswers is not a social media website. We are a question and answer site for information.
You show them that you are responsible enough to take care of your self while you are out with a friend.
If I wanted to tell a friend about wikianswers, I would tell them that it is a website where people ask and answer questions. Then I would give them the URL and say "Go look at this link. I have a lot of fun here, maybe you will too."
Find a friend you like, and psot something on their message board.
