What is it?
A StartingPoint is a site that makes first-time users familiar with the concept of wikis in general but also with the concept of your wiki in particular. In this way they learn that a wiki is NOT Wikipedia but Wikipedia is a wiki. And they know from the start how to use your wiki and where to find help.
Provide the URL
of your StartingPoints with your Invitation
what your wiki is for (e.g. product documentation, project management etc)
what space / webs it might contain
what should be documented there.
your wiki culture, e.g. everybody can offer criticism, but should also be able to be criticized.
give hints how to start e.g. editing a page, or filling out the user profile.
provide links to additional help to your wiki (editing…).
