A few words of thanks would be greatly appreciated.

iPad: An online service to send WhatsApp messages

WhatsApp Messenger is one of the preferred IM applications for mobile platforms. It is available for free (for the first year) for most mobile OS ( BlackBerry , Android , Windows Phone). But that's not the case for the iOS app. It costs $ 0.99 and you can download from the Apple Store.
However if you don't want to buy it, there is a webpage that allows users to send WhatsApp messages from an iPad or iPhone.

From your iPad, open Safari and go to http://www.webwhatsapp.com/SendWhatsApp.php
Select a country
Enter the contact number
Write your message and click on Send.
