I'm using Newscoop 4.2.3, and on my dashboard the 'Your articles' widget is empty, although I have submitted at leat one article. I'm logged in as a 'journalist' for test purposes but can logout and login again as 'admin'.
In contrast, if I look at 'Content > Search' I can see not only my articles but other people's as well, and I appear to be able to change their status, as long as they haven't yet been published.
