I've been fixing bugs the past several days, and things are running smoothly. I've even got IE8 rendering all right. Please keep sending comments, suggestions, and bug reports; Scott will handle them, unless they're linguistic or Flash-related; those I'll plow through when I return, like a boulder through miniature bowling pins.
There does seem to persist some problems with the Genius not loading enough words. So words may not load in order of readiness, because some might be skipped. This is mostly harmless, so if your review bar sticks, don't worry. You can refresh the page every once in a while if you want to get to the ones it passed over.
