...Click the Globe and it will take you step-by-step through the process of creating a label (which appears in the message in blue) and adding the link (which will be hidden).
I remember that it ~used to~ work this way for me...but for some reason it no longer does. Now when I click the link button and I insert, I'm presented with a two-part link. For example, if I want to enter a link to point to flyertalk, I would get the following back (with the 'URL' replaced with 'ZZZ' for demonstration purposes).
[ZZZ="http://www.flyertalk.com"]http://www.flyertalk.com[/ZZZ]
The link I want is listed twice. The one within the double quotes is the true url. The 2nd one is where I can replace the text. In fact, the 2nd half is still highlighted so that I can replace with text of my own choosing.
[ZZZ="http://www.flyertalk.com"]here[/ZZZ] becomes
here
If folks still have the "old style" link button that walks you through the process, I'd love to know how to get that back.
