As I mentioned before, I think that a better use of time for churchly open-source software users than specialized Linux distros is making templates that open-source software, like OpenOffice.org, can use.
But I have a hard time getting my head around what kind and range of information a small church need to gather, and which forms are essential. There are a lot of denominations and communions out there.
Paper forms -- either PDFs or real copies -- would be helpful. Can you send me those your church or temple uses? Please email me at blog at boyinthebands.com if you have something you want to send me. Thanks.
