The yellow triangle usually represents a Javascript error, the details of which are not typically divulged by most modern browsers unless you ask for them. The way to do that, in most cases, is to either click or double-click on the triangle. Thanks, by the way -- I really appreciate your help.

An improved messaging system, which will include private messages, is fairly high up on my punch list. But it will be after the launch of the new site. I have a handful of things left to do before launch, which shouldn't take too long. I'm aiming to be ready by September 1, however since I will be out of town from the 5th though the 10th, I'm going to try to do the actual reveal on Monday Sept. 12.
The messaging overhaul is a big project, and will probably be a month or two in the making. Hopefully before the end of the year...
