Josiah, Of course It makes to have persistent rights, but see my recent post and about surveys. If you have a large number of potential contributors the document file model may not be the best.
Keep in mind tiddlywiki documents can be read only yet also interactive so a survey respondent could export their responce and send it in separately (I hope to automate this with mailto and attachments). A single use password says go here make changes and save them. They are throw away, they may be in a link, can only be used once and you can see if they have being used. You could allow people to get one on demand, even transparently. If you control the issuing of the password you can manage serial users and workflow. The are not for everyone but they have some great use cases. I hope this stimulates more feedback Tony -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
