[support] Forcing username pattern

[Larry Garfield]

Hi folks.  I've a question that's come up on a number of my sites now.  I'd 
like to be able to disallow users from selecting their own usernames, ever, 
even on signup.  Instead, I want to expose various profile fields (or custom 
fields via form-alter if necessary) and then base the username off of that.  
E.g., first intial and last name, all lower-case.  Does anyone know of an 
existing module or mechanism for that, or a common pattern that could be 
turned into a module?

"If nature has made any one thing less susceptible than all others of 
exclusive property, it is the action of the thinking power called an idea, 
which an individual may exclusively possess as long as he keeps it to 
himself; but the moment it is divulged, it forces itself into the possession 
of every one, and the receiver cannot dispossess himself of it."  -- Thomas 
Jefferson
