Couple of questions about forums

1. How do I stop receiving emails telling me someone posted in a thread I'm following? Alerts would be sufficient for me. I thought I had found out how but I'm still getting emails.

2. Why do I occasionally get a forum error message "You do not have permission to view this page or perform this action" even for threads where I have already posted?

Thanks.

 

Thanks for the prompt reply. That box is already unticked.

Yes, that's it.

 

Okay, I see how to do that for each individual thread. Also I notice that not all my watched threads have "email" in the lower right corner, so maybe there was a delay between my unticking and receive email notifications of replies and it actually taking effect. Will see how it goes from here on out. Thanks.

Edit: or maybe unticking that box doesn't stop emails from previous threads, only ones going forward.
