I didn't think it was completely filled when I bumped it at 9:50am, and the second reason was because these group buys, used to be run and posted to in this AG forum. Brewers come to this section of the site to see if a buy is active. this will tell those who look here to go to the ingredient section.
It would be nice to get a sticky posted of the bulk buys being moved to that section
hope this helps
