Once a tool is published, within a published project, it is available for contributions from the participants. However, for any reason if it this needs to be removed, below are the options available on the different tools of EHQ.
Forum / Brainstormer / News Feed Tool
These tools can only be deleted if no participant contributions have been received. Once a contribution is received the tool cannot be deleted as a database has already been established. To then remove this tool from participant view, simply unpublish the tool.
Surveys / Quick Poll / Places
These tools can be deleted at any time. Or you can choose to 'unpublish' to retain contributions but keep them hidden from public view.
Guestbook / Q&A
These tools can be archived at any time.
The tool itself has to be removed from the Manage page.
