On the Opera forum it is not possible to post more than once every 45 seconds. This measure is designed to make life difficult for spammers. I wonder if it would be too hard to implement here to prevent double or triple posting caused by slightly tardy server response at times.
Try sending your ideas direct to FE,I posted in Speakers Corner about the quantity of emails,and within 48 hrs we got the new message appearing when you click the envelopes.If its possible,then it will be done. ;-)
