While we're on the subject, why do you send an email for every single new message? Wouldn't it make more sense to send one message/thread since your last visit (as most forums do)? |
The way it should be working is that it will send you an email only once since the last time you read the thread.
As far as the error that you received. I fixed some other errors with this page. Not sure if I hit that exact error so let me know if you are still getting an error with the watch list page.
