I am feeling for the profile managers at this point who, while the 'criticism' is constructive and I think thoughtfully done, have not invited the wider community to comment :)
Thinking about the source list... while the guidelines point us in the right direction (to Evidence Explained), perhaps a (future) elegant solution is to have a full style guide (like you see at universities).
Here's an example:
UniSA Harvard
That's an extreme example but a 'wiki' I think would be incredibly useful. I'm currently creating an EndNote library to EE standards and, while it's extremely time consuming to create, once it's done, it's done. Having a WikiTree-specific style guide would make it easier on members who are unfamiliar with referencing standards. You wouldn't expect a university student to reference perfectly without one.
While the site does have links to Evidence Explained, it is not a perfect source as the forum constantly refers back to the book (fair enough too) and, as it is American in origin, often does not contain enough information for international users.
Just a thought...
