We have been having some trouble with our newsletter software, some people using it for less for useful purposes. Unfortunately, it only comes with a Google Captcha, which we keep getting messages for it being broken. So we have had to turn it off for the moment and are looking at the upgrade with some more and better options for sending out the newsletter. It may take a couple of days, as it is a major upgrade from the previous version, but it looks reasonable enough for us to go ahead with. Just a couple more tests to make sure I haven't broken anything major.
