You mean like how to share this stuff with your friends? Well there's Skype if you're all like that.
BUT THERE IS
DISCORD (<<<click that)
Discord is completely free and can be accessed by just an internet browser. Also has a phone app for on the go shitposting.
We have our own
chatroom with our very own Coral Mayhem room (still filling it up though).
You can view the old Coral Mayhems
here. (warning: the people talking about the images in question were very much younger than they are now. viewer discretion advised.)
