I know I'm repeating myself, but the fact that links to other sites (or even CS recipes that are not part of the forum) open in the parent tab/window rather than a new tab/window is making me yell at my computer.
The Community site is shaping up to be awesome, but it is still a very dynamic and object-rich website. Having to reload the entire page every time I click on a link (because I forget to right click and open in a new tab) is awful.
Other than that, I'm liking it a lot. I am even getting used to the Hot vs New for topics, but I still think the comments should always be arranged in chronological order from oldest on top to newest on bottom.
