(In the Thinkwiki example, their use of categories seemed backwards to me at first. However, it is useful to know whether a given laptop supports a particular feature, and the category listing at the bottom provides that nicely.)

The NUT HCL was never meant to fill that role, but a completely free-form wiki might not be as useful as a custom web site. In either case, we would need to have some decent spam protection. The NUT Trac instance was hit fairly hard a while ago.

Sometimes it is for the better - Powercom shifted to a standard USB HID PDC interface (which was easier to support in NUT). However, APC apparently dropped support for a lot of variables from their HID PDC interface in favor of their proprietary Microlink protocol (see apcupsd.com for more information).

Just to let you know, I am looking at various wiki software, and aim to 
set up a wiki where we all can document the output from our different 
UPSes with different drivers, I think it will help people who are 
looking to buy UPS and want to use it with NUT.
I hope to have the wiki up during October, but cannot promise anything.
