There is a great opportunity to share your faith with people asking on yahoo Answers. Google it. find the religious section. People asking questions about God every minute every day. We need lots of people answering.
I just noticed that Craigslist has some of the same in their discussion forums. But it can be a very tuff crowd that is watching. Lots of athesits there mocking any Christian related quetsions and answers.
Have you tried it there?
(By the way, I found your original post funny. "....on yahoo Answers. Google it .....") HAHA. Using Google even for yahoo answers.
