You can design your own splash page as per instructions given here :

Now you also have ability to upload templates and keep them private to your own account. No other user will have access to these splash pages. This ability is especially useful for non-english speaking countries. You can create and upload a splash page in any language you like and make it a default in your Wavespot.

In order to upload a private splash page, go to "User Settings --> Private Template"

In the next screen, you can upload a zip file containing a custom splash page. This splash page will remain private to your account and can be shown to all visitors.
