I have exactly the same thing. You can search the list archives for my  
discussion with Kyle and Francois about it. Try: “periodic updater”

If you need some example code, maybe you’d like to take a look at the  
code on the SVN repo at [http://svn.berlios.de/svnroot/repos/motiro](http://svn.berlios.de/svnroot/repos/motiro)

Cheers,

Yea, I was thinking about adding a cron job to script/runner. Or even  
not script/runner. But you can create a simple script  
that loads the Rails environment. I mention that because I couldnt  
tell if my scripts were loaded properly through runner.

For example (most of the script, no runner used):

require File.dirname( **FILE** ) + ‘/…/…/config/environment’  
ctr = 0

# Iterate through the user links

# and extract the various keywords.

for link in UserLink.find(:all)  
end
