Hello:

	I have a server running on my YDL machine that has a directory that 
it puts text files corresponding to new users in occasionally.  The text 
files have a tag in them which indicates the last time a user logged 
in.  I want files older than 30 days or so to be deleted.  Assuming I 
can write a program that will check and delete the files, how do I get 
that program executed on a regular basis, probably every 24 hours?

Thanks,
Chaz McGarvey
