I assume you meant saying that the Base64 encoded Data in the Report variable
must be adjusted to reflect the actual hostname etc., or is params.php
accepting _any_ report that looks reasonably valid?

For reference, the decoded data in this example is:
<?xml version="1.0"?>

<SreScanReport Version="3.7.116.0">
        <UserInfo WinDomain="" WinUser="roni" WinUserCatalog="C:\Documents and
Settings\roni.LENOVO-4FFEF4E3"/> 
</SreScanReport>

cheers
FX
