Can I make a wiki that my students can read but not edit?
- Although you used to be able to do this in older versions of Moodle, it's not really in the "spirit" of a wiki and is no longer possible without tweaking permissions. A Book might do the job just as well, or a simple Page.
- However, if you really need to do this then remove the student role from mod/wiki:editpage and mod/wiki:createpage when you create your wiki. See forum discussion here: 
How can I grade my students' wikis?
There is no in-built grading facility in the wiki but you can manually add a grade item in the Gradebook called (for example) "yourwikiname" and enter your grades there.
How can I get groups and groupings working for my wiki?
Check your version of Moodle -this was a problem that has now been fixed - see tracker entry
Can I export a wiki?
While it was possible in earlier versions of Moodle to export wikis, for instance as zipped files, this is not the case in 2+. There is a tracker entry here MDL-24439
