If you've looked at Informix Zone you may have seen it has the facility for anyone to create an account, start an Informix blog and post articles. Christian Winterhager has done just that... his first article: Raw Devices on Suse Linux is an excellent introduction to setting up raw devices on Linux, and includes a Python program for automating dbspace and raw device creation.
I like the concept of a commons where Informix users can contribute articles, opinions, etc.. My suggestion would be to consider opening it up so anyone with an account can start a blog without the approval step and see what happens.
Update 11/13/06: See Eric's response in the comments. Thanks Eric.
