Discussion2 has been in beta for a few months now on Slashdot. Initially available only to subscribers, it now should be available to anyone willing to login and click the checkbox at the head of every discussion. It is far from complete: IE doesn't work (patches welcome, but since only a quarter of you use it, it's not a huge priority) and performance is lacking (you want a fast computer for larger discussions) but it's already an improvement for most users. Read on for some notes on what we have planned.
