I know the blog exists for this purpose, but a lot of newer users don't check the blog to see what's going on.
Why not also have a sticky thread that only you, Reed, can post in on the General forum? You could even simply copy and paste what you put on the blog with updates.
I suggest this because there was no real thread for the Dustcatcher update; it was mentioned inside another thread that I think was unrelated at the time. Now if someone wants to find out about the update, they have to click several different threads in order to find out about it.
If you have a sticky thread at the top, you could even put in a FAQ for each. I'm kind of surprised at how many people didn't and possibly still don't understand that actual drawings aren't going to get removed via the dustcatcher, but I do keep seeing people get stressed out and angry over it when it turns out it's not even happening.
