Via Seth Godin is this reference to EditMe, which is a commercially supported wiki service. Most wiki software is open source, and can be a pain for non-programmers (like me). EditMe offers hosting, support and a better interface for a reasonable fee of $5 to $25 per month. I was involved in a recent healthcare project that used a wiki, and the learning curve was a bit steep for some people. EditMe seems to be an easier tool to use, which would mean less time to accomplish the goals of a collaborative build project.
