Ok it may be possible all those emails didn't go out afterall - even though according to the log it emailed about about 100 people, nobody has logged in at all from that list since then. Generally when reminders are sent out, the aftermath is MIA members showing up out of the blue to have a look around.
Maybe the database error prevented them all going out?
Will be relieved if this is the case since I know those two members didn't get spammed afterall
