I learned this handy and useful skill from Landen Michaels, so please please thank him for it. His home page is http://stressedwriter.gather.com/. This is how Landen explains it:
"The HTML code for a clickable link is:
[a rel="nofollow" href="LINK"]TEXT[/a]
except that you should use the carrots < and > in place of [ and ]. I did this, just in case the Gather email system would turn my HTML code into an actual link."
So, type <a rel="nofollow" href="
and then copy and paste the URL for the page you want to link to
and then ">
followed by the text you want to make into the link,
followed by </a>
and be careful not to add any extra spaces.
If you have any problems with creating a clickable link, blame Landen. All I know is that this works very well for me when I send a Gather Broadcasting group e-mail and want the e-mail to link directly to my latest post.
