Cell based church

In our church - Bergen International Church - we've always had a vision to be a cell based church, but we've struggled with it. How can the cells become more than just another activity?
To all who are interested in the issue of cell church, I can recommend an Anglican website: http://www.anglicancelluk.org/

On Sunday we will do yet another attempt to promote the cells, and hopefully manage to get so many newcomers that one of the existing cells can become two - at least.

A couple of years ago we decided to increase the frequency of our worship services from bimonthly to every Sunday. Being a small church with an average of fifty attendants, is this too much? Would it be better to return to a rythm of fewer worship services and focus more on the cells as the basic meeting place?
