first off, please allow me to say that MODx is simply empowering and amazing. I love how it lets you so easily create your own site designs etc and still gives you the backend to make changes easy for yourself and clients. The best part? its not obscenely bloated and overly difficult to make subtle changes with like so many other CMS out there.
In either case, I was curious if anyone could steer me to a starting point for using the handy quick edit feature to enable anonymous users to edit certain fields within the site content. The idea is not so much to create a wiki, but rather to give some wiki style functionality, so that visitors can change certain content at will - anonymously

. I use the term wiki loosely and want to emphasize its not really the ultimate goal at all. Just a way of describing a general functionality I want to emulate within the actual MODx site structure, as seamless as possible.
Now here is where it gets complicated - if possible I would like to preserve the admin/specified users privilege to use quick edit on more "static" or sensitive site content - things which not all users should be able to access.
Is this something that can be fully accomplished with the user roles (if so i must be blind?) or will it require some recreation of snippets and some custom coding? Im guessing the latter of the two, but anyones advice on getting started would be wonderful.
Thanks!
