The forum software that we use at the FsDeveloper website has the option to automatically send a congratulation email to user that have their birthday at this day. Of course this only happens if the user has entered his day of birth. Sometimes I get a reply on these automatic messages, usually just a quick thanks. But in the last two days I got about 3 such replies, which is a lot more than usual. So this made me wonder, would people born in March be friendlier?
