excommnication anyone gone through with it

out of curosity i was wondering has anyone here been excommunicated and also what was the process? is there a certificate given out and stuff. had a conversation with a complete stranger that still ha sme thinking and also reading up on it. i tried to talk to few friends about it and either they dont care,to stupid, or dont get it. so this forum is full of intelligent minded people(im no being sacrastic i am being genuwine).
just wanted info and feedback and how too for curiosities sake.
