 How to setup a Cron job? 
-Download exim and cron from cygwin setup. Run exim-config (don't forget to launch your cygwin terminal as
-Administrator). If asked for a daemon name, type ntsec. Also, if cron complains about sendmail,
-symlink /usr/lib/sendmail to /usr/sbin/sendmail.  Then link /usr/sbin/sendmail
-to /usr/bin/exim. Alternatively, if you have an smtp server, you can download and configure
-ssmtp.  Run ssmtp-config
-as Administrator and link /usr/sbin/sendmail to /usr/bin/ssmtp. After the email has been configured,
-run cron-config as Administrator.
+First, make sure you downloaded cygrunsrv, otherwise the cron setup will only work on a per-session 
+basis! Also, make sure that you have an email correctly setup.  In particular, cron relies on the
+/usr/sbin/sendmail script. If it does not exist, cron will not send emails. Most email management 
+systems will create this script, but you need to check on it. 
+Run cron-config  and fill up the questions. For daemon name, type ntsec. 
+Be careful, make sure that you are running your terminal as Administrator, 
+otherwise your settings will be only user-based. 
+How to setup email? 
+
+Preferred way is through ssmtp. Download it on cygwin, and type ssmtp-config.  If the ssmtp 
+daemon does not create /usr/sbin/sendmail, be sure to create a symlink from the email client 
+to the latter file. Be careful, make sure that you are running your terminal as Administrator, 
+otherwise your settings will be only user-based.
