It is a dead project, but for someone who has issues with complex web formatting, it's an excellent tool anyway. Use the older version of the Suite or the Netscape composer; they don't insist on playing stupid CSS games. (CSS was supposed to make our code shorter and easier to use; most of the software that uses it produces brain-wracking code.)

Basically, Composer is too dumb a program to be able to screw much up, which is why I like it for my users. Contribute is better, because it costs money.

I just installed NVU for windows, which looks like someone took Mozilla composer and did things to it to make it reassuring for Linux users. For the average non-geek... *sigh*
