I am thinking of content such as:
- link to forum rules/guidelines
- how to reset your OpenOffice profile (link)
- how to report/vote for a bug (link)
- What additional info could be helpful in order to reach a solution (list of typical info required, posted inline - not a link - so it can be adjusted for the case at hand.)
...
I have seen a few other web apps with this kind of tool available. In our context I guess it would only be in the way for the regular user, and perhaps clutter on smaller screens (mobile devices), so it should probably be enabled only for volunteers and higher "ranks".
