[drupal-devel] Storing arbitrary data for a user

[Dan Robinson]

I have a small amount of persistant data I would like to associate with 
a user and would like to avoid creating a new table to store it in.  I 
have come across variable_get and variable_set - which is great - but 
probably not appropriate for what I'm doing.  I've also seen 
user->categories, but can't find any doco or info on what this is.

Thanks,

Dan
