A project website that uses a blogging tool to create a website.
It seems that Wordpress is a particularly recommended tool for project blogs that are intended to work as websites because it supports a publishing workflow where you can have multiple authors of pages and one editor who publishes. It has been described as a website tool that is also good at blogging rather than a blogging tool that can do websites, which sounds much more suitable for research projects in my opinion. It supports the creation of a static home page, which seems to me to be a requirement.
