Welcome to Rokkenjima, Cherry! There’s plenty for you to read here, probably starting with the newly translated arc, Someutsushi! Just read the arc and post your feelings about it! Doing so may win you a fun prize, so please, join in! Participating in the tea parties is probably the best way to get involved around here, so please, give it a try! You can also catch up on our past tea parties by listening to our podcasts (which you can participate in). There is a podcast for all of the stuff rereleased on Steam (so the Higu question arcs, Umi question arcs, and Meakashi)!
You can also talk about all of your favorite Umineko memories by posting in the various sections per episode. For example, if you want to talk about how cute Sakutaro is, you can do that in either the spoiler or spoiler free section for episode 4. We also have a place where you can talk all about your favorite scenes for both Umineko and Higurashi. You can also talk about the various characters you like best, whether it be Bern, Beato, Keiichi, Rena, etc. And if you just want to talk about your feelings on Higurashi or Umineko as a whole, we have that too.
That’s not the end of the fun either. There are also places to talk about mystery novels (Hello there, Sir Arthur Conan Doyle), books in general, writing in general, fanart for Umineko and Higurashi, hobbies/talents, gaming, even everyone’s cute pets.
And if even that isn’t enough for you, you can check out other 07th Expansion stuff like Rose Guns Days, Higanbana, Hotarubi, and TRianThology! I hope you enjoy it here~ 
Oh… And one more thing. In case you haven’t heard yet, WTC 5 is in the works! This teaser page is all we know so far, so come join in the speculation! All aboard the hype train! Choo-Choo~
