As the technical advisor involved with the Community Church of Chapel Hill electronic presence at:
we've gone through several rounds of volunteers, use of simple web page hosted by the ISP associated with the DSL service (Mindspring, now part of Earthlink) at the church then to local hosting "deals" and discussions about advanced features and revamping the web site.
Now we are returning to direct relationship with our DSL provider, [c3h.wikispaces.com a Wiki based web service], and a separate e-mail and domain name hosting service (Network Solutions).
Hope to share and be inspired by others as this wiki evolves.
Cheers de Mark
