http://docs.indymedia.org/view/Global/NewImcPageImprovements

i only tried to put what seems to be current practice, if 
someone on imc-communication has an idea of what people
there think should be a better list of global lists, 
or a better interpretation of  h.  and  i. of the membership
criteria, please feel free to correct/update the TWiki.
