When I click the link to go to the first unread post in a thread, it might take me there the first time, but all subsequent times I click that link, it'll always again take me to the post it took me to the first time, even after a thread has moved on many pages, and I've visited all the new pages and read all the new posts. Even hours after I first clicked the 'go to first unread post' link in a thread, and seen all the new replies, the next time I click the 'go to first unread post' link for that same thread, I'm taken to an old post many pages behind where I last was reading in that thread.
Just a convenience thing, but one that's only convenient if it works as described. Without it functioning properly, I have to sort through threads to find where I last was, to continue reading them.
After the forums crashed yesterday, I though that maybe this issue was related to that, and that after the forums were re-established, that this might be fixed. However, this issue is still preset.
