I’m my church‘s webmaster and have been doing a fair amount of work on the site lately. We’re hosted by Zettai, which is a really awesome web host. They specialize in Plone and Zope hosting.
I installed PloneCollectorNG, an issue-tracking system, to keep track of maintenance. We just put the sermons on-line. People with accounts can read the newsletters since 1999, in PDF format. The newsletters are making the Data.fs backups of Zope very large: around 70 mb.
