Converting users to enter content on crowdsourced site

I've been running a crowd sourced quiz site for a while:

http://www.quizmash.com While I'm getting plenty of quizzes taken through google search traffic, my conversion rate to entering a question is pretty bad.

Does anyone have any suggestions on how I can improve this.

I think your navigation, layout and terminology is confusing users. I think you need to make the following improvements:

• make the front page and main navigation focused around the three main reasons visitors are there (Start a quiz, add questions, see leaderboards), I suspect the general user doesnt care about your twitter link, searching for questions, about, help (move those all to a sub navigation somewhere else). The front page could be split in two, one side to answer and the other side to add questions
• remove the add questions interface from the answer screens as again it is confusing (see aside below)
• I think the term "mashed" is a bit confusing when you mean "created"

Aside: I just tried your link above and then picked the first
topic which took me to:

http://www.quizmash.com/tags/Science/quiz

 

As a non logged in user I have the following issues:

- you are randomsing the answer display but the answers people

 have written include "none of the above" which wont always appear as

 the last answer

- I have a "well done" section on the right when I haven't

 answered a question?

- if I scroll down I get a message "You have answered every

 question we have on Science.", I haven't answered any?

- if I continue to scroll down I can now add a question, but I am

 in the middle of answering a quiz, that doesn't make sense to me
