UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Watched List Email

Hello,
at the moment my users get one email per watched forum. So far so good, but after you've threads watched in a 40 forums or so you'll get 40 mails. In 6.5 there was only one email which summerized up all of them. Is it possible to have this feature back?

Regards,
Thorsten

Rick mentioned a rework of the e-mail system.

I think he can cover the details better
