Our DW campaign needs a wiki! There are a million options, which one should I pick? Here’s what’s important to me:
* wiki functionality, easy cross-linking & new doc generation. I believe this rules out Google Docs.
* not a jail; documents should be easy to export from it
* solid. Not buggy. My last campaign wiki was on pbworks and the rich editor was a buggy nightmare.
* (edit) free is very nice.
* (edit) all participants need to be able to edit it.
