But could they implement the "Choice" on the prefs page? 😉 (yes, probably)
I would much rather the AppleJiveTeam spend their precious man hours fixing my email notification problem that has been ongoing since before they undertook to fix it beginning in JANUARY - or all the other forum bugs like Phantom Posts (a post that one knows exists from an email notice but is not visible to YOU but is to others), "You are not allowed to create or update content",
- OR -
providing a facility to change "skins" on ASC like most robust bulletin boards
you might take a look at "Installing and Using Styles" link on https://www.phpbb.com/styles/ - it has the "architecture" of how they think one should build a "structure" of elements (different 'files' for Header, Footer, thread, forum, etc. - would correspond to 'separate' CSS like I proposed = "ala carte" choices for Stylish?)
