I made two posts in the Coffeehouse forum yesterday and now they are both gone. I even edited one of them. They were in these threads:
I'm located near Portland, OR and the globe at the top of the page says the server is in North Central US if that helps.
Also I noticed when I click on the Forums link above the "Start A New Thread" title the list of the forums does not include Coffeehouse. Are you discontinuing this forum? It's still listed in the Forum menu at the top of the page but if you click on just "Forums" you get the same abbreviated list.
