Help! How do I take and get rid of the pm's after I have looked at them or replied to them?

For now, they are here to stay.

You can't, they are there to stay.

I don't think you can. I read in a post before that they just stay there and the new one stay on top. But not 100% sure. Lets see what everybody else has to say! I like to know to!
Thanks for asking!
