Thanks beigemartin, I wouldn't have known otherwise.
I'll reply here as well. Whilst I can't solve the "people don't reply to PMs" / lack of courtesy problem there does seem to be an intermittent mail sending problem that affects some messages.
We have fixed it and currently it seems ok but we know there's a problem if we're informed by you. If you do notice a problem it would help if you could please email us at firstname.lastname@example.org
