Thank you, hdr.ecssh, for your great feedback! I'm also creating a web service on my own while juggling personal tasks, so it's always been difficult to complete it as much as I want. But I've found that using Gnuboard can greatly reduce development time. In this lecture, I used a real estate community as an example, but the actual use cases can be expanded much more diversely. Features like member-to-member messaging, shopping cart functionality, and payment systems are already included in Gnuboard by default, so you can link them directly from the admin page. I'm providing a linkage guide in the latter half of the lecture, so I hope you listen to the end and get some ideas. Additionally, we are considering an extended lecture for in-depth learning of more detailed functions, so please look forward to it. Thank you!
