KISS method
Hopefully you have 'copied' the URL location first.
Click on URL symbol. Paste into line. Make sure you do NOT have 2 http://
in the line. If so, delete 1 of them. Press enter or click OK.
Format is [QURL=xxxxxxxxx]xxxxxxxxx[/QURL] - The first xxxxxxxxx is the location it goes to, the second xxxxxxxxx is the name that appears within the post to click. Delete the 2nd xxxxxxxxx and put in the name you want to appear for people to click. Make sure all the brackets stay where they are originally.
example:
[QURL=http://www.example.com]http://www.example.com[/QURL]
to change to:
[QURL=http://www.example.com]My example[/QURL]
in the Post it would have 'My example' as the link name to click.
NOW TAKE ALL THE Q'S OUT OF THE COMMAND (CHANGE QURL TO URL)
I had to add them to be able to demonstrate the command without it taking effect.
