Please be advised, we've experienced trouble with members changing their email addresses associated with their profiles. I've just worked through a case with a member who changed their email address and did not receive a notification email from Proboards.
At this time I do not have an explanation as to why some ISP's are not sending notification emails thru from Proboards. My only thought is because of strict spam mail filters at the ISP end.
So, if you need to change your email address associated with this site, use a general account like Hotmail, Yahoo, Gmail etc. ISP email accounts like RR, Comcast, Verizon, Sympatico, Rogers etc may filter the Proboards notification email.
Sorry for the trouble but there is nothing we can do about it.
