Subscription Assistance

[Peachkins]

I recently subscribed to a thread for the first time. I set it to have an e-mail sent to me every time a new post shows up. I have subscribed and unsubscribed several different times, and have tried a couple of different e-mail accounts. Every time, I will get e-mail notifications for so long, and then I won't receive any more. I already checked the FAQ addressing this issue, and this is not related to a problem with any of my e-mail addresses. I have already checked the settings on those to ensure that I will receive the notifications I am supposed to, so I can only assume the problem is with this site. Has anyone else experienced issues like this and/or have any advice on how to get this to work properly? Any help is appreciated. Thanks!
