I think the most common requests for the new site are: forum subscriptions, and easier access to search.
Tonight we enabled the notifications_forum module, which allows one to subscribe to forums and threads by clicking the "Subscribe to..." link at the top of either the forum or the thread in question. You can also manage your subscriptions on the Account page under the Notifications tab (the first one; I'll figure out how to fix the label on that eventually...right now, both issue tracker notifications and other notifications have the same label), so you can unsubscribe easily and selectively, based on your desire for email from the site.
For site search, I've punted for the moment...I would like for there to be a search box on every page, and, in fact, that was the way it worked when we first launched the site. But, I soon realized it caused a black bar across the top of the screen and logo on some browsers, so I disabled it until I could figure it out. I haven't figured it out yet, but I have put a Site Search link in the menu at the bottom of every page. Search is quite flexible, and for logged in users, you can choose to selectively search forums, documentation, or other parts of the site. It's also reasonably quick, and seems to return reasonable results. I'll keep working on it, and will get a search box enabled on every page as soon as I figure out the CSS problem that breaks for some browsers.
Licenses are now instantly available for new purchases. The software repository and the license checker all query the same database as the website, so they are never out of sync. There's still some display quirks, and a usability for downloading the install script could be improved.
Existing licenses that need renewal or upgrade are still requiring manual intervention; if you find yourself needing to renew or upgrade, email me or open a ticket and I'll try to get it dealt with quickly. There's a bit of a backlog for that (though for most folks, the license extension we gave everyone keeps their license active long enough for this to not be a big issue), so be patient (but feel free to holler if it's urgent!).
Thanks for all the great feedback, so far, folks. We'll keep working on this until it is nice for everyone.
