I had some experience building simple websites with WordPress, but learning GNUBoard properly this time made me realize how great it is. Unlike WordPress, where you have to search for additional plugins, the features already implemented are so diverse. Especially the powerful administrator functions, which are sufficient to cover small to medium-sized projects with just the basic settings. Core features like bulletin boards and member management are provided automatically, which is really convenient. After setting it up myself, I think the scalability is also good, so I'll study it more and use it in various projects in the future. Please provide an advanced course as well.
