Michael Bush's WebsiteAnnette, to post a website, you click the second icon from the left in the icon row. That will give you the url tags (in brackets, [ url][ /url], but without the spaces, they wouldn't show if I didn't do that).
To make the words clickable, highlight them, click that icon, change the first closing bracket to a '=' equals sign, paste your URL and put the closing bracket there. I find it odd that you have to do all that, most forums convert without having to do all that, but it's the only way I have found to be able to do it.
To create the highlighted link to Michael's website above, I followed my procedure and got code that looks like this (spaces are inserted at the beginning and the end to make the whole thing viewable):
