Facebook is better, but this thread is fine too. Don't worry about re-posting in the FB group if you've let me know on here. Because I run both the thread and the facebook group, I'm notified when people post. I've had a very bad experience in the past where I wasn't informed regarding some tournament information that changed the day before a tournament, which was pretty vital, and I went by information I assumed was up to date (considering as I heard said information from the person in question in private messages just days before). So the new Smashboards is great for avoiding this. Not to mention that I now won't run an event unless I run the whole show.
The benefit of the facebook group, is that I get updates straight to my phone which is always on me (even at work or when I'm out with clients). It also allows me to read them on the go and archive the messages in my work planner.
