A couple of conversation starters

Wizzards are indeed a very useful and potentially time-saving tool. Your example is for adding good content. However, wizzards can also be used for instructing how to remove bad content. Above I tried to define content quality by five requirements (it's just a try). What could help is making such wizzards for all of these requirements, then translate them for all projects. For example 'how to deal with POV/unencyclopaedic/biased/etc content'.

A "Report a problem with this page/article" link or icon on every page, that leads to a pop-up wizard for advising how to handle problems? I'd say "yes" to that. It's something we could do with the present-day setup.

One of the wikis (polish, maybe?) has something like this. Might be worth checking into.

@FT2: it is a good idea. Of course there should first be a wizard before there can be a link to it though. @Philippe: I checked the Polish wp but couldn't find something like it. Perhaps Piotrus can help us out.
