I created a lion socialization website called Lion’s Den using UMW Sites, here is the link to it: https://teagandkc.umwsites.net/
To explain the difference between DoOO and UMW Sites, I would say the UMW Sites is a simplified version of DoOO, with limited themes, plug-ins, and features, that is best utilized for small projects meant for only one class. Because of Sites limited themes and plug-in’s, customization and creativity are stunted significantly. Additionally, it is limited in the sense that you do not get a domain or neighborhood, you only get one house, so it is harder to expand if you want to pursue multiple projects. Because of these reasons, I would recommend Sites if someone had only one class that they anticipated needing a site for and would not mind the limited customization. Because it is simpler, it could be more useful for people who want something more user-friendly.
