<p>This is by-design.  There is no reputation conferred to you when accepting an answer that is community-wiki.</p>

<p>What is more important than rep is if the answer best answers your question - if you feel it does, then you should mark it as the accepted answer.</p>

<p>Don't get too hung up on not gaining +2 points for accepting the CW answer; as you contribute  quality posts (which you are doing!), you'll get this back many times over.</p>
