When you activate LiteMount and it can't find a usable mount, by default it will display the error message, "You can't mount here."

This might be because you can't mount in the current location, or because you are moving/falling and don't know any instant-cast mounts.

If you know how to write WoW macros, you can instead get LiteMount to run your own actions when nothing else is available. To do so:

1. Open the LiteMount options to the Macros panel.
2. Select the "Unvailable" tab.
3. Select either your current character or a class.
4. Type your new macro into the text box.
5. Check the "Enable" box.

This does not work when activating LiteMount using a macro on an action bar, due to Blizzard preventing macros from calling other macros.
