I’ve been into Wikipedia for several years, and all my friends know this. I *still* find myself having to explain to them in small words that that “edit” link really does include them fixing typos when they see one.
So my suggestion: tiny tiny steps like this: things people can do that have a strong probability of sticking.
Anyone else got ideas based on their (admittedly anecdotal) experience?
