I'm using WPMU but you will find some options the administrator should set and really should take affect for each user from the website. Does wordpress possess a spot to store these global options? Can anybody point me to sample code?

Thanks!

My first instinct is always to create my very own table to keep these options. Then you've complete treatments for when, where, by whom the information is utilized ... globally across all your MU blogs.

So far as sample code goes, I'd suggest beginning within the codex or attempting to walk-through this tutorial.
