On the old forum, the sort buttons at the top of the list of threads said Recently Updated, Start Date, Most Replies, Most Views, and Custom.
Now, they say Topic, Latest Post, Replies, and Views.
It is clear that Latest Post = Recently Updated, Replies = Most Replies, and Views = Most Views, but it is not clear that Topic = Start Date. I actually at first thought it was "sort the topics in alphabetical order" until I tried it.
I think it should be changed to Start Date, Topic Start Date, or Topic Start.
