[SWLUG] Carmarthen meeting reminder - TONIGHT

[Dafydd Walters]

Unfortunately, I can't make it tonight - working late in Cardiff.

Unfortunately, broadband problems (brought on by the bad weather, I
reckon), have prevented the usual automated reminder my PC normally
sends out.

For anyone who's interested, the cron job I set up for the reminders
just runs the script below every day. I've added the following two lines
to cron to make it happen:

0 4 * * *>..>.../home/dafydd/bin/swlug-reminder 'Mon' 15 21 'Carmarthen'
'Tuesday'

5 4 * * *>..>.../home/dafydd/bin/swlug-reminder 'Tue' 1 7 'Cardiff'
'Wednesday'
