I know it won't apply to all coops, but I will say that for the current Aether coop, I made it basically as large as I could based on part availability. One of the reasons for this was so more people could get what they wanted. Heck, we're into the 3rd hour now and there are still around 100 left. I think that is some kind of record lately. If it was the same as the last one, it would have closed in the first hour again. I knew there were some from the last one that wanted in and there are a lot that were in the last one that are in this one too. Hopefully more people can take advantage of the cool equipment RJ designs. Of course I had the advantage of this not being my first coop so I was able to increase the quantity to help more people out.
I will say this from the coop manager perspective...like others have commented, I really did not know whether to add the other people or not. What if they didn't want them anymore. What if they couldn't afford them now, etc, etc,. I started out with confusion, then panic, then frustration. Not sure where I went from there. Plus, if the person comes on and posts later, now they have double quantities or wrong quantities. Definitely a big can of worms. I would only take orders from actual individual posters for what they themselves wanted. It IS the only way.
If you know someone wants some, give them a call and let them know, but they should be the only one to post.
