The idea is: we are running an electronic dance music blog, our posts will be about specific artists. We would like to create a feature that we can assign an artist 'profile' to each post, for example: http: // prntscr.com /7vypj (as you might see on the right, there is a widget with the artist information). So, we want to create a directory listing, including the information about each artist (like his Twitter, biography, Facebook) and we would like to display a part of this listing as a widget on each post. Also, we would like to enable our visitors to edit the information without being logged in (like Wikipedia with a log). Each modification must be moderatated and / or approved. We are running a WordPress installation, any suggestions as a plugin?
Most author plugins will let you add a bio, but they will all require you to be logged in to make changes. Isn't it a risk to let people make mods to the bio without being logged in? I see it as an open door for hackers, but that's just my opinion.
