After creating an account, you are told:
== Welcome, <username>! == Your account has been created. Do not forget to change your <site name> preferences. Return to <some page>.
This is about the worst possible call to action - why would most users, straight after creating an account, suddenly want to visit a page containing several tabs full of settings, most of which are completely baffling to a totally new user?
If we keep it, we need to at least get rid of "do not forget". It really doesn't matter if you forget to change preferences.
