to post a link (itīs very easy):
mark the URL, shown in Toolbar (example), with
pressed left mouse-button --- it will turn to blue (shaded) -
and drag with your mouse to message reply window.
...
or position your mouse arrow on mini-icon left to URL in toolbar
(a description will tell you something, like "Drag and drop this icon...")
- press left mouse button and drag that icon to your message reply
...thatīs all
...good luck, we all be newbies sometimes, somewhere
