What is Google sites?
Google Sites is a Google service that makes it very easy to create simple static pages (the G Suite Knowledge Base is a Google Site). This allows users to quickly create good looking temporary pages that do not have to be added to the Thalia website itself (e.g. information pages about study trips).
Can I create a google site for my committee/society ?
Yes, every G Suite user can create their own sites. However, if you want to have the site available on a thalia.nu domain (e.g. gsuite.members.thalia.nu), you need to ask the Technicie.
