You can find the official release at icculus.org. We currently have source code (mainly for the Linux crowd) and a Win32 binary there; we're still waiting for goldenegg to get around to compiling a MacOSX binary. As soon as that goes live, we'll post an update in this thread.
Most questions can hopefully be answered by the built-in help; if not, we'll try our best to answer them. And please, don't bother with comparisons to other emus, it's a pointless waste of time and bandwidth.
