Speakers : everyone who is sharing something new in the discussion
Administrators : those who are taking charge the discussion + the editing work
do you think that would be fair?
If someone is leading the discussion, and also sharing interesting things like others speakers, technically he participates in 2 differents ways. Or we can suppose that administrators are already paid enough ! ;)
Anyway, it's not really for me to judge whether this is fair or not ! :D
