Currently we have our themes and configurations grouped into three categories. Fvwm 2.x Standard format Themes conform to the guidelines in the How-to Submit page, and have been tested and found to function under Fvwm version 2.2.2. Fvwm 2.x non-standard themes do not conform to the standard format, and may or may not work without hacking. Fvwm 1.x non-standard group contains all the Fvwm 1.x configurations available.
