First make something then decide about it. As I wrote before.
Lets define the tchnical structure. 1. GPL + FDL + no binary blobs + 100 % libre. 2. Linux from Scratch or Gentoo ? 3. Binary or source or binary base system + extra software as source (source or emerge) ? 4. 32 or 64 bit or multilib (new systems or old systems) ? 5. XFce or LXDE or ... ? 6. Target market like education, health, science ... 7. Components of the base system ? 8. Website software, bug tracker, Forum / GNUSocial instance ? 9. Where to host from whom ? To be continued ...
Let a core team decide and let the user base make improvements.
To make Core Team first call people. If 3 decide over others error is the end.
The call was before ... Make a list about your nickname / planned nickname. About the function you like to make and the time you can spent (fulltime / parttime / x hours a week). You must not have the knownledge now but you must be ready to learn this things. Never make promises you cant / would hold ! If the core team are 3 people then ok. What we want, a new Ututo or simple talk months about that we talk ? If people are unhappy then they will switch the distribution.
