<p>Your profile shows that you've asked a bunch of questions but haven't accepted any answers. Instructions for accepting answers can be found in <a href="http://meta.stackexchange.com/questions/5234/accepting-answers-what-is-it-all-about">Accepting answers what is it all about?</a></p>

<p>The system is basically trying to help you out. When you accept answers the people who answered the question get a little bit of reputation (the score by your name). Think of it as a "thank you". Your badge shows "0% accept rate", which means you haven't accepted any answers at all, so it looks like no one has been able to answer any of your questions. From what I can see people with decent accept rates get good answers, as they tend to follow up and accept people's answers as the correct one.</p>

<p>Clicking on your username will take you to your user page, which will show what questions you've asked. If someone's given you an answer that answers your question, give them a +1 vote and check the checkmark!</p>

<p>You can use the search to find out which questions you have not accepted yet by searching for <code>user:me hasaccepted:0</code> </p>
