Duplicate Emails Sent When Subscribed to Forum and Topic

Hi,

On our board I'm currently subscribed to one of our forums but I'm also auto-subscribed to any thread I post in. The problem is that whenever someone submits a new post in the thread I'm subscribed to which is in a forum I'm subscribed to, I get two separate emails. One for the new post in the forum, and another one for the new post in the thread itself.

It's a little annoying having two emails that link to the same post. It would be nice if it would check if you're subscribed to the thread and only send that email once and not the other.

Thanks
