phpPanelAdmin is an open source tool for the management of online (access) panels or similar sampling lists or communities.

phpPanelAdmin works with PHP and MySQL, both of which are free.

phpPanelAdmin's features to administer an online panel include:
- create a panel sign-up form from a template
- automatic set-up of the panel database

- view, modify, and delete panelists' data
- delete and clone variables
- draw samples
- send e-mail to samples or individual panelists
- export panelists' profile data
- panel statistics at a glance
- identification of duplicates
- create and manage e-mail templates

Download the manuscript (send an e-mail to receive the password that is needed for opening the manuscript) on phpPanelAdmin that I submitted for publication as a journal article. Please cite the manuscript/article in all work that benefitted from using phpPanelAdmin.

If you use phpPanelAdmin in conjunction with the open-source tool Generic HTML Form Processor to track panelists from the panel into your study, follow these steps:

• When sending the e-mail invitation to a study out of phpPanelAdmin, after a ? append a unique identifier called "id" for each panelist to the URL of the study, for example: http://www.yourstudy.de/page1.php?id=uniqueidentifier
• The first page of your study (for example: page1.php) should have the extension .php instead of .htm or .html
• Insert this line of code into the first page of your study in between the form tags: <input name="id" type="hidden" value="<?php echo $_GET[id]?>">
