The primary purpose of a website is to offer information. The format of Word Press sites with the WA emphasis on content is perfect for the needs of many non-profits.
When presenting the idea of creating a website to a group first emphasize the Blog.
This could be a forum for addressing issues connected with the work of the particular non-profit. Not only would people understand the work done by the group, but they would be able to react to some of the issues facing the non-profit. Everything from staffing to budget could be discussed in the blog forum.
Build a sample menu based on the activities and staff of the organization.
A menu heading might be "community service" with another heading being " monthly meetings." Another heading might introduce staff or the organizations executive team.
Help the organization think of all the information they could present through the website.
The "About Page" could offer a history of the organization with information about future plans.
A Menu Item called, "Members' Page" could highlight the work of members on a regular basis.
Use your imagination as you present the idea of an easily built, easily maintained and easily edited website.
As you present the concepts of a website, demonstrate on a mock site that you have put together before the meeting. Everyone attending your meeting should have the chance to add menu headings and suggest blog roll topics.
Once people understand that a website is a great way to present their message to the community, you can demonstrate how to monetize the site.
