When I want to place a link on a page and link it to a certain domain (url) and so that it opens in its own window, it doesn’t work. I used the link tool by html and by visual both give the same results, no link appears on page.
Add the following code into your post in HTML mode
<a href="http://www.mydomain.com">New Window</a>
Replace mydomain.com with where you want to point to and change the text New Window to something that explains about the link.
You can select a piece of text and use the Insert/Edit Link button in visual mode to insert the URL and just below where you key in the URL is a tiny check box that says ‘Open link in a new window/tab’ check it.
