The point of not making the pack public is that you need additional permissions from the mod owners. Currently we have permissions for a private mod pack on FTB. The pack was going to be released yesterday, as the RAM we needed to be able to run smoothly arrived, however during installation there was a hardware malfunction. So Hyper has been spending today trying to fix it and get the new hardware. The server should be up, ideally, today, but most likely within the next few days. We only got permission from FTB today which is why the pack hasn't been made public, as well as not having had the RAM until yesterday.
Sorry for having not kept everyone updated, there's just been so much going on and so much to do!
I understand that it's annoying being kept in the dark and waiting, but please remember we're all volunteers, with lives and jobs and that we are all trying our best to make sure that there are as few problems as possible before launch.
Generally I'm always on the forums looking out for questions etc... so if there's anything anyone wants to know, PM me or reply and I will do my best to answer
