I look forward to seeing what you come up with. I especially enjoy reading through development threads, either the theorycraft like when @Drbretto was setting up his pack, or the aftermath threads which break down the challenges along the way and lessons learned.I'm planning to publish everyting, either in a 'behind the scenes' thread after I finish my project, or if I run out of time you'll see a 'I just totally flunked at making a modpack- but heres everything I learned' thread.
Watching the pack come together step by step and one epiphany at a time is fun enough, but learning about new solutions to existing problems, new mod choices, and seeing the real time decision making process for whether a certain mod will make the cut or not helps me rationalize similar choices when it comes to my own custom packs. Not to.sound cynical, but it's nice to see other people struggle with the same ideas I've struggled with, if only to ice the bruise on my ego.
The aftermath threads are nice too, particularly if they have details (or like to where those details exist) on how to accomplish tasks abnormal to the generic kitchen sink pack. The cautionary tales of what not to do, and the rabbit hole configuration stories help prepare me mentally for the challenges ahead in my own experience, and help curb me from having to make those (potentially spirit crushing) errors on my own.
If you're interested in sharing your development in progress, by all means let me know.
