Does exactly what it says on the tin. Some of the nonsense contained herein may be very loosely related to The Sisters of Mercy, but I wouldn't bet your PayPal account on it. In keeping with the internet's general theme nothing written here should be taken as Gospel: over three quarters of it is utter gibberish, and most of the forum's denizens haven't spoken to another human being face-to-face for decades. Don't worry your pretty little heads about it. Above all else, remember this: You don't have to stay forever. I will understand.
So how did it go then ? I bet it went really well and you can't believe all all the things you were so worried about. But half the people who said they were going to turn up to help with things like photography etc. didn't. It's usually the way.
