Where can I build a Q&A website like...

[yasin]

...Yahoo Answers (or what services are there out there)? It'll obviously be on a smaller scale, based on the exact same principle of registered users asking questions and other users being able to answer them.

I would use a forum script and modify it so it takes points for asking questions and adds them for answering them. If you want, I can help you with this task, thomas_clarke1@msn.com is my email.
