Yes, I was going to say just that--deeplinks are still working.
The front page says there are 2 million some-odd files in zero folders, leading me to speculate that the user interface has simple been disabled.
This appears to have happened only this afternoon, and there's fewer posts on the LUGNET forums about it than in this thread. (The owner of BrickShelf only posts on LUGNET. That's how it was last time, right?)
The change is one of two things: Brickshelf is FINALLY making the transition to a pay site, or it is going offline for good. We should be prepared for both.
