Re: Limit Article Editing to Owner and Admin
Absolutely true. I made that mistake with my test account. But when you assign the author and type the first letter of the student's name (I assigned all my students with a firstname.lastname account), tiki will (at least in mine) try to populate the field with a student name with that letter. I let it look up the values and click the suggestion to complete to assure a perfect fit.
As for losing edit access, I've marked the box that disallows a non-admin from re-assigning the article to another. And since I have overall write access, I can help them out with things they are confused about or have "messed up"
