|
|
This program gets the members from the MySQL Database that need renewal.
|
|
By starting with --mode=day you can select only those members that need to
|
|
renew today.
|
|
With --mode=year you get the members that need to renew this year, i.e.
|
|
whole 2011.
|
|
|
|
One can send email, too. Use the --send-mail switch to send email.
|
|
|
|
If you want to test your setup, you can use --one-only=your@address.com to test
|
|
whether email actually works or what From address is used, which is
|
|
configurable with --from-address=other@address.com.
|
|
|
|
In order to work properly, you need to have your MySQL client configured
|
|
properly, i.e. ~/.my.cnf should be set up with the appropriate
|
|
credentials:
|
|
[client]
|
|
host=button-back
|
|
user=anonvoting
|
|
password=foobar
|
|
default-character-set=utf8
|
|
|
|
The reason to call MySQL client and not use the Python library is
|
|
mainly, that the MySQL bindings are not installed.

Dear %(firstname)s,

the last time, your GNOME Foundation Membership was renewed, was on

The term of a membership is two years.

If you want to continue being a member, you have to renew your

Please see http://foundation.gnome.org/membership/ for details.
