How do I change the domain name that is bound now?

[opentype]

There is a Change License URL button for the purchase in the client area.

Where is this url?

[LiquidFractal]

In your Client Area, click the Manage Purchases button beside your existing URL.  Scroll to the bottom of the page, where you'll find a Change Licensed URL button.

Note that you'll have to uninstall the IPS suite from your existing URL before you can change the bound URL.  You can also only do this I think once in a 6 month period or something (there will be information on the page).
