Here are the steps:

1. In the body of your post, type the text for how you want the link to read in your post (OR just paste in the actual URL address but you still have to complete the rest of the steps below)

2. Highlight that text (or the URL you just pasted)

3. Click on the "Insert/Edit Link" icon (looks like a chain link) in the editing bar above (the icon will be grayed out until you highlight your text)

4. When the Insert/Edit Link box comes up, in the "Link URL" field, insert the URL of the web page where you want the link to go

5. In the "Target" drop-down field ALWAYS select "Open link in a new window" (If you don't do this, moderators may edit your post to do it for you)

6. In the "Title" field, you can leave it blank or type in a brief title for the link (this is only for the benefit of the search engines in the background and isn't really necessary)

7. Click the "Insert" button

Done.
