Regarding email notifications
I know some where concerned about the check box for subscribing to a thread being defaulted to on although with the post it is not checked, so maybe that has been fixed.
I responded to a couple posts last night that were going like gang busters, but never received a notification until a little while ago.
On the previous format I would get them individually and able to click the link to get back to the thread.
Below is a screen shot of what I received a little while ago. If this is the way it is going to work it might be OK. Instead of getting a notification for each post...get one after a whole bunch and multiple threads in one notification.
The only problem is the links go to an error page.
