Since there are many users that create new credits without adding a small profile or role info about the new credit, something like "If you create a new credit (espacially with the "about/subject" field, don't forget to add some profile info about the new credit."
should be added to the wiki page
Sometimes it's really hard to guess the correct meaning of the credit, and there will be many wrong assignments.
I know that this won't really help, but it should be included, nonetheless.
Some users actually read the wiki ;-)
Thanks for the feedback - that's a good point. I'll get that added to that document. We're thinking of ways to make those guidelines and help documents more accessible, hopefully we'll have more on that soon!
