It is still available, they just changed something on their website so Roger's link doesn't get there anymore. Here is a link that works.

Special note to Baba: To make a link in a post
1) Copy the address from the window you want to link to.
2) After you click "reply" or "quote" in this forum to post a reply, look for the globe with chain icon above the post window. It is next to the smileys icon.
3) There are two dialog boxes that pop up. The first box is the one you paste the link into. The second is the name you want the link to have. You can simply use the paste again so the full address will show up in the post. Sometimes that can get rather long though, like some Ebay listings.
