Go to the site you want to be posted in the message. Click on the address in the browser address box then right click and select copy. Then make a reply at this site. When you want to put in the name or word referrring to your site, select the http:// button. It will bring up a box. Type in whatever you want to name the site and hit OK. A 2nd box will pop up. In that box right click and select Paste and it should put the address of the site you want linked. Or you can type in the site manually, but it is easier to copy and paste, IMO.
