Del Vento So is in Bulgaria also common to use fish on April's Fool?
Actually not. The fish catching extension comes by default with the fishes, maybe it was made by someone from Italy 🙂 BTW, I can import any pictures I want and they will get animated moving back and forth like the fishes and I thought maybe I could import some pianos 😀 But I've been pretty busy these days and just installed the extension and enabled it with the default settings. If it proves interesting, I can keep it and we can organize "catch the pianos" rounds, etc. What is curious though is this extension initially started as an experiment by a Flarum developer to test various functionalities of the forum but he realized it approached a game, so he released it and it proved very popular with Flarum users.
In Bulgaria we call it "Lie's Day" (because you try to trick someone into believing some BS but it shouldn't be a very obvious BS, so he has to believe it somehow and if you succeed then you will say "Happy April the 1st!") or "Joke's Day".
