There is an option to be informed by e-mail, of personal messages. Is there such an option to be informed of updates to a message 'thread'.
I think this would be very useful but I can't find any way to set that up.
The question was not if private messages can be sent via e-mail But the answer to the question is Sorry no not at this time. I have used bulletin boards that you can choose the option to be notified by e-mail when somebody replies to a thread and it is a usefull feature.
Edit....oops just re-read it properly and I guess the feature does exist
