I would say that signatures are the biggest problem, especially for new and unregistered users. We explain how to sign in the welcome message, on the editing page, in the style guide, in the unsigned template, in a graphical image....and people still don't get it.

In terms of where to sign, some people like messages up top, some people like them down below, that's an individual thing and difficult to tackle.

And notifications...you should know where the new messages are on your own personal talk page...
