i've just had a look at your 5 posts, and the times they were posted, times replies were made, and then the time you made this post.. they were all made within an hour last nite.
now, the notifications only work on the first unread reply, so in otherwords, if you are signed in, and you have a look at a reply, you wont get a notification. if you however logegd out, and waited until today to check again, you will have most probably gotten a notification email, that is, if you checked your email.
also, please make sure you're actually subscribed/being notified of posts. the default setting is that its turned off.
another point is that the emails will only be sent to your registered (and verified) email address as listed in your profile, so dont bother checking your other 90 email accounts, its only going to be in the one account registered with this account.
here is a picture of the notification page under the profiles - yours may look different (most probably blue) as i'm testing a new theme for the forums. in fact, yours does look different, i've just had a look and you have all the options ticked.
even though those settings i have turned on are turned on, you wont get notifications unless you select to be notified.
scroll down a little bit further in your profile and you'll see this -
those are the topics you are currently subscribed to/being notified about.. notice how the 2nd one has a little envelope next to it? that indicates that you have been sent a notification about that topic.
so, check your email that is registered on the forums with this user account, and if you dont have an email from antrx notifying you about that particular thread, i'll look into it futher.. there could be an issue with your mail server requesting an SMTP authentication - because i have changed the emailing setup to a PHP based mailing system, there will be no SMTP authentication happening.
on the other hand, if you have got a notification email, my advice to you is to take a lay off the coffee, listen to something other than commercial radio - and relax.
