A regular, unregistered reader pointed out one change with the new software: previously a "Today's posting" function was available to all readers.
This has disappeared and my friend was unhappy, having found this a useful function. In the new system, there is a similar function near the top on the right: "View posts since last visit". However, this is only available to registered members. Thus, if you want to have this facility, you will need to register here
It's a quick, painless process. Some people have found the optional "Profile Information" section duanting, but don't worry, I don't understand some of the references either.
