- INTERNAL: Changed how we were limiting email sent to some domains, to use the MX server domain as a key for limiting instead of the receipient's domain. This will affect all messages to GoDaddy hosted domains, orange.fr/wanadoo.fr, earthlink/mindspring/netcom and a couple others. This will hopefully allow us to keep under per-connection limits imposed by these email service providers and avoid getting temporarily blocked for trying to send too much email at one time.
- INTERNAL: Technical debt cleanup of web page templates. An ongoing process.
