Having problems figuring out where to enable..

There's apparently not a user interface for this module. It is enabled on the "Story" content type by default, so you can use that for testing. If you want to change that setting, you can go to line 82 of the module file (node_to_word.module) and modify it from 'story' to something else. It's also disabled by default for all roles, so you'll need to enable the permissions unless you're just testing as the superuser.

Unfortunately, this module is lacking some other relevant features (CCK, document formatting of some kind). But that's the short guide to getting it working.

*ETA: I didn't mean to change the original question to a revision under my own name. Sorry about that!

Yeh, that's something I've been meaning to fix for a loooong time. I'll see if I can schedule a day on this module to sort some things like that out. CCK support will *not* be part of that, because the template solution works for now - it needs refactoring as a display type, but I won't have time to do that. But being able to choose content type is a feature I definitely want to add quickly.

This has now been done and is available in the 6.x-dev version.

As described in #2 above, only the functionality to select which content types are enabled has been added at this stage. Other functionality is welcome in patches, please open a new ticket for such new features.

It will be released in 6.x-1.1 when #926530: Update from 6.x-1.0 to 6.x-1.x-dev will break permissions has also been completed.
