Okay to open a site in a new tab or window you can use the following code

On a button
Code:

On a frame
Code:

You can change the URL (the first parameter, in our case "http://www.supperbas.com") so it will point to a different webpage.
The second parameter allows you to decide whether you want a new page to be opened or not.
If you use
_blank = A new tab or page will be opened (depending on the settings of user)
_self = Will open the webpage link a regular URL
_parent = Will do the same as _self but if you use iframes _parent will refresh the whole page where _self will only refresh the iframe it's in!

So if you want to support iframes use _self if you don't want it to be embedded in an iframe use _parent (when in doubt just use _parent or _blank)
