Is it possible in the frontend to edit unpublished items that belong to other users?(yes, I've searched the forum, but didn't find a answer)

I have exactly the same issue, I wanted to do this for a client. Have you come across a good solutions?

 

Thanks

I have developed a new view to acheive this. If anyone looking for this solution, please get in tocuh with me.

two new links added to user module, which displays...

 

(1) unpublished items by logged-in user

(2) all unpublished items (if logged-in user has granted permission using k2 user groups),

 

no, hack. completely new view added to templates files. so not mixed with other K2 files, very clean and professional enhancement to K2 user view. you can get in touch with me using skype id = thewebdesigncompany

This seems like a great add to K2.  I'm very interested, and sent a Skype request as well.
