Messages dont go away =(?

Question

I started a chatroom kind of thing, where i sent a single message to a whole bunch of people so we can all reply back to each other. The only problem is that now we don't want it anymore, but none of us can find a way to delete it. Everytime someone says something, we get a message and it is really starting to get annoying. Other than blocking those people, is there any possible way to get rid of this!

PS. I'm the one who started it, so maybe I have a certain button to do this.

Answer 1

I've had the same problem. So far I haven't found a way to delete it, either.

The worst part is, I keep getting emails from Facebook every time someone replies to the message. (I don't want to edit my preferences to stop that, since I still like to get emails when someone sends me a normal message on Facebook)
