...It's not very user friendly...
Why?
It's difficult to tell by the front page which topics have new posts. On the old forum, when you were logged in, topics with new posts were indicated with a bright orange icon.
On this new main page, I can't figure out what's what. There's a symbol on the left that looks like a triangle with a line through it. Some of them are gray, some are blue, but it doesn't seem to reflect accurately one way or another which ones have had activity.
This is going to take a lot of getting used to. I realize this was done in an effort to improve the site -- and while the effort is definitely appreciated, there is an old saying, "if it ain't broke, don't fix it". I saw nothing wrong with the site the way it was.
Just my two cents....
