I'm loving it too! This is more like other forums I use/have used, I like that it doesn't "take away" posts that I've just read when I click off of them...sometimes I want to go back!
Navigation is a breeze for me....I can look at individual forums for subject specific threads, or I can click "What's New" to see what's been posted, and go through several pages instead of just one. It really seems to me that most of the way we do things has not changed, just the titles of the buttons we click has.
It's very nice, a lot of thought and hard work has been put into it, and I, for one, appreciate it!
