I have really enjoyed leading Resurrection Online and trying out new ideas. Sometimes I have a hard time explaining what is in my head. I found a great website that helps distill thoughts to a one page plan. I first read about this concept at Visualize your business plan with Plan Cruncher and then went to try it out myself at http://plancruncher.com.
While not specifically designed for churches, I found it helpful in getting a fresh look on Resurrection Online Micro Churches.
Plan Cruncher – I recommend it.
