Excellent thanks chaps.
I've just pulled down the latest code base and all seems to be working again.

Anyone else experiencing double posts on their forums? People presses "Submit" twice (or reloads page and opens compose window with the local-storage saved message). I've done it myself a couple of times. I think it can happen when the websocket disconnects.
A possible solution could be to generate a hidden unique in the the form which is matched when submiting.
