Communion: how often is too often?

A pastor friend of mine dropped

by yesterday to talk about communion.  He increased the observance of communion at his church from 4-times a year to 6-times a year.  At our church, we have communion on the first Sunday of each month -- 12-times a year -- plus on special occasions like Maundy Thursday and Christmas Eve.

So, the question is -- In non-liturgical churches, how often should a church have communion?  What does your church do and why?  Do your members believe that having communion more often makes it special, or do they think that having communion less often makes it special?  Or is that the wrong question?  Let me know what you think, because I'm sure other churches struggle with this also.
