Post registration to webpage?

Is it possible to collect registration data from the user and do a post to a webpage from NSIS. If not does anyone have any ideas as to how this data can be submitted to a website before completion of an installation? Thanks in advance

To get data from the user you can InstallOptions (See Contrib\InstallOptions\Readme.html). To send it to the server you can use NSISdl or simply open the webpage using ExecShell open "http://www.myserver.com/register.php?username=a&key=aaaa".
