Merlin, you can type in the BBC code for the URL using the code found
here.
Go down to URL in the alphabetized list and the code is shown there.
Basically you use the hyperlink button in the compose message and change the first bracket following the first [url] to an equal sign, then put in the left facing bracket after your url (IE: http://stevedgood.com/community/index.php) then type in the text you want to have someone click on after that bracket and before the ending bracketed url.
Hope that is somewhat clear
. If you go to the link I mentioned you will see what I mean.
