The Official FVWM Homepage - Links

Here's a few other sites (besides the official one) that have FVWM info:

And here's a few others that have info on programs that are designed to work with FVWM in some manner:

The Dotfile Generator Home Page - A program that helps you generate .emacs, .cshrc, .fvwmrc, etc.
John Lapeyre's FvwmConf
The TkGoodStuff Home Page - A Tcl/Tk Program that performs like GoodStuff/FvwmButtons.

And here's some window managers that were originally created from fvwm source, but PLEASE DON'T ASK QUESTIONS ABOUT THEM ON THE FVWM LISTS! Rather, contact the parties responsible for them directly:

SCWM - The Scheme Configurable Window Manager
Bowman - A NeXT Lookalike created from 1.24r (link no longer exists?)
AfterStep - A continuation of Bowman
Fvwm95 - A hack of an fvwm2 beta that looks more like (shudder) Win95
Fvwm decorations - A collection of fvwm screenshots and config files
Fvwm decorations - Another collection of fvwm screenshots and config files
Fvwm decorations - Even more fvwm screenshots and config files

And here's an excellent site with all sorts of window manager information and comparisons (new location):

Window Managers for X

Be sure to vote for FVWM in the voting section! :)

And don't forget about Newsgroups:

comp.windows.x.apps - for discussing and announcing apps like FVWM.
comp.windows.x - for general X11 discussions and advice.

And how about an online version of the ICCCM:
