When i get the "no new posts" error it has an option (on chrome on android and firefox on ubuntu) to see posts from the prior 24hrs. I just click on that and it works fine from there. And yeah that admin(s) aren't super active when it comes to approving new buyer threads and some other ones but they monitor enough to delete escalating threads pretty quick and someone out there keeps sending Gustavus/alloy2/Proton/Snowman on vacation so they are around. And suggest thinking of the forum less as a business of which we are customers and more like a community resource which itself requires some modest resources to function.
Fwiw have made four support tickets (all to get threads approved) and reported one post (several posts on one thread to be more accurate) and never received a reply to myself but all were acted upon, if not immediately. It's not something to lose sleep over.
