SolvPDF is a utility that lets you add a popup message to your PDF files (ebooks, user manuals, etc.) and to automatically open a web page when someone is opening or closing your PDF file.
Then this program is going to change how you do things FOREVER. You see, after a whole month of searching, swimming through adobe's 274 page user manual, reading forums and doing surveys on people... I have finally developed this tool which, when used, actually allows you to...
* Add welcome messages when people open your eBook
* Add "good bye" messages when people close your eBook
* Change the icon of the popup messages
* Automatically open a web site, or a popup window, when someone is opening your eBook
* Automatically open a web site, or a popup window, when someone is closing your eBook
