We all are on these type of exchange lists and it would be useful if the questions could ALL be listed at the top of the email. In this way I could glance quickly down the list and see if there are any questions I could answer or were interested in following. Ideally the list would be hyperlinks to the actual question but that is not nearly important as listing all the questions at the top.
You can sign up for email alerts by topic and will receive an email each day with all new questions and answers. Is that what you are looking for or something else?
