Continuing the discussion from What if a group changes name?:
What would realy help people like me, that, while not completely newborn babes, lack the long history with the MB community: a collection of guidelines that are considered best practice, but without the full weight of a style guideline. At best with a rationale for each paragraph.
People are complaining that the style guides are too detailed, but I often find them not detailed enough: a particular question of mine is not explained there, but has been discussed to death before on IRC/lists/forums.
Collecting this knowledge in a central place would also allow evolving it along with the capabilities of the software. Like when artist credits (or aliases, etc.) made a number of practices obsolete.
