Please note that Hotmail's automated mail screening system is once again rejecting emails sent from the Realcent server. This is not the first time and probably won't be the last. Hotmail is generally not interested in fixing anything manually, they would rather let legitimate emails bounce than correct an error in their filters.
So if email notifications are critical to you, please consider using something other than Hotmail for your Realcent account.
If you do change the email address for your account, the forum software requires me to manually reactivate your account. I will do so as quickly as possible but I can't be at the computer constantly, so you may be unable to use your account for a short time after changing the email address.
