Notification navigation broken
This is, in part, just a function of how navigation works in general on these forums, but I thought the people still working on the forum programming should take note of the fact that when I get an alert that someone has replied to a discussion in which I've taken part, that's not inherently bad. But if I click on that notification, I expect to be taken to the new replies.
Instead, the person clicking is taking to the default page for that discussion which, if popular, won't include any of the most recent replies. And if you scroll tot he bottom and click on "more replies," the interface does add new replies --- but in the process of adding them, it automatically scrolls you right back up to the top again.
Nor is there a button for revealing ALL replies. instead you scroll to the bottom, click more replies, get autoscrolled to the top, scroll back down to the bottom, click more replies again, and get returned to the top again, repeating several times for longer discussions.
This is tedious and is exactly the opposite of what people reading a forum want. You hit more replies to see the new stuff, not to be shoved back into the heart of the old stuff. And you hit the notification button to go to the thread in the first place to see the new stuff, not the old stuff.
Both the notification button and the "more replies" button should reveal all the newest replies, and take your browser to those new replies automatically.
The entire point of hiding replies is to make navigation easier, but with this set up it does not. I would rather have to scroll past hundreds of messages once than scroll past the first 20, then return to the top, then scroll past the first 40, then return to the top, and so on. Eventually I'm going to have to scroll past all those hundreds of messages to get to the new ones anyway. The current interface just makes it so that I have to do so over and over and over again.
Targeted links from your notification page, a "reveal all replies" button, and the ability to maintain one's place on the page while revealing new replies are all necessary here.
Pagination rather than hiding replies would also be much preferable to the current system, though with the other 3 options implemented pagination could be considered optional.
