Unfortunately, Kagi.com, which I have used for decades for handling software registration has gone under, owing to vendor fraud. A very sad day. For the time being, I will handle licensing directly via Paypal.

What is RiddleMeThis?

RiddleMeThis is a program for creating and maintaining questionnaires, administering questionnaires electronically (either on a computer or online via the web), and collecting and exporting the data for analysis using any suitable software package such as SPSS or Excel.

RiddleMeThis's features include:

RiddleMeThis questionnaires can be hosted, via the RiddleMeThis Online Runtime (free with RiddleMeThis) on computer workstations (Windows or Macintosh) or on any webserver that supports PHP 4.x or later (i.e. most web servers).

All of RiddleMeThis's features are supported through a straightforward graphical user interface. No scripting languages are required.

RiddleMeThis Forum

I've just set up a forum for users of RiddleMeThis. It's very empty right now... This forum will replace the (very occasional) newsletter, and -- I hope -- help make me more responsive to your feedback.
