Hi,

I decided to take a different approach to hiding content (module to let user chose if a node is private). I'd rather hide users so I won't waste UGC.

I've stumbled on:

http://insready.com/node/54 and http://drupal.org/project/profile_privacy

But I'd like to go further: I'd like to completely hide user existence.

I recall just one place where a user name appear in drupal stock: Posted xxxx by yyyy

yyyy is obtained by theme('username'

but of course there could be hundred places where other modules avoid to pass through theme().

That's OK... I could submit patches to every module I find that skip theme(). Is there any other place where I could intercept this information?

Still overriding theme_username is something that put this functionality in the theme rather than in a module. Is there any better approach?
