When I first started using Version 3 I couldnt find the Compose Email icon. At first I went to top left corner, & chose New>Compose Email. I can do this whatever section I am in. Not just messages. Now I have learnt I can right-click on the main toolbar and choose the second item down - Customise Toolbar and tick Compose Email. This puts the icon on the tool bar for me to click when I need it.
