QuickHelp for the buttons. Can automatically display first unread item in a mailbox on loading. You can specify which files to show in the mailbox list. It requires AmigaOS 2.04 or better to run - you might get away with running it under 2.0, but no guarantees. Under 2.1 and higher, you get localised dates.
Full instructions are in the doc file.
It comes with a spiffy Installer script now, too. You will, of course, require a mailbox file. It's exactly like ADMail, only more so. Feel free to distribute this, but do NOT make money from the distribution. Or I won't be your friend any more.
