Welcome to Rokkenjima!
If you wish to discuss Higurashi and Umineko, we have threads (spoiler and non spoiler) dedicated to each arc, and to the series in general! Feel free to add in, or read other peoples thoughts!
And, if you want to read more 07th expansion, might I recommend you try Higanbana No Saku Yoru Ni? The community is currently reading and discussing the first night, with a podcast putting the first three chapters on dispay, and a second one coming with episodes four to seven as the main topics.
Lastly, we have other threads for nonrelated 07th expansion things like favorite foods and music if you just want to try and get a feel for everyone!
Enjoy your stay
