Communication

In the past 9 years I can't count the number of times that our staff has talked about how to increase our level of communication. This would be among staff as well as to and in the congregation. It just seems like a never ending problem and one that we just can't get on top of. So I wonder if we are missing avenues that are available for communicating or are we sending conflicting messages?
We have updated our web site and worked very hard at keeping the information up to date and accurate. We send out a large newsletter every month and fill our worship folder each week with information about what is happening in the church. Still people say things like, "I didn't know we were doing that!"
Could it be that we are telling people to many things so they aren't hearing any of it? But if we start cutting things out what will it be? How are we going to let people get the details out in adequate ways?
I'm sure there will be more on this one later as I just don't know what the answer is to this one.
