Is anybody else completely dissatisfied with this new forum?

Yes it is going better, but it is still slow in some cases. On this thread (with 95 messages), clicking on the "Go to latest reply" takes more than one minute before the end of the thread is displayed on my computer. And Firefox complained twice that a script on the page was taking too much time to process.

Another feature that is still missing imho is a read/unread status. When I come to the forum I'd like to know which thread has messages I haven't read, and in each thread to jump to the first unread message. Without this each time I come to the forum I have to guess from the approximate date and time I was on the forum last time. And even like this it isn't easy, because the thread list still shows the date and time of the first post in a thread instead of the last one.

Something rather annoying also happened to me today. I was writing a (long) answer and when clicking on the "Answer" button, I got the message "This thread/question has been closed. It has a best answer selected!". So two questions:

1) the selected "best answer" is not visible on the thread itself. In the thread list I can see that the question has been answered, but there is no indication once we are in the thread itself.

2) why is the "write an answer" box still present on the page if it is not possible to answer?

But keep up the good work, it's a step in the right direction!
