Adding article user bottom in a module?

Hi All,

I like the feature to ad the user information in an article at the bottom.
Now I was wondering can I get this also in a module to show up..?
I know I can have a user module, but that only shows the avatar, if I am correct.

I am working on a weblink section on my site and just want the (super) user info on the bottom of all web links and links categories..
If its not possible maybe a suggestion to make such a module, in the future?

Thanks for your time..

Appie
