This isn't directed at the OP but for what it's worth (and I know NeilF, tireless maintainer of the "subscribe to be notified of livestreams thread", has a pet peeve about this too) I really have to point out that there's a livestream at the same time EVERY Thursday evening so I've kinda run out of sympathy for people complaining that FD don't do enough to let them know about it. Also, there was a forum thread about tonight's Discovery Scanner posted last Friday so there's been a whole week to find out about this.
Neil complained in his thread about the couple of hours short notice they gave, but they announced it last Friday, he just didn't see it until 2 hours before it started.
