1. I can but try. :)
2. I'm not entirely sure that Paul's aim of being a Secretary Moderator fits within the role of being a Secretary. IF he wishes to change the bylaws then that sounds like something Adam is campaigning against letting Secretaries do, so that will indeed be interesting. Remember, at this point the secretaries have not overstepped their role in any way, so the need for this might not exist. Plus, the voting members are able to throw random votes on whatever they want at any time, so if a bunch of people say "Hey, I don't like what that secretary just did" and all the secretaries refuse to do anything about it, then a vote could be held about that. That is entirely hypothetical, and exceedingly unlikely. That's why there are three, not one or two.
I find the whole secretary power paranoia thing to be rather odd and incredibly monotonous. It seems to be based on literally nothing, other than the secretaries doing what they've been asked to do, and that one "Probably ignore Dracony's vote on his own expulsion" thing that was reverted a a few minutes/hours later. I don't think we need to dedicate any more time to worrying about secretarial powers being overstepped.
Moving on, you make a solid point here: "There is currently no documented mediation process or code of conduct which defines appropriate and inappropriate behaviour." A Code of Conduct would have helped the Aura conversation on both sides. People wanted to know specifically which rule he broke, and of course there is none, because we don't have a set of rules for behaviour. The heavily anti-CoC stance taken when the conversation came up blocked the FIG from having a CoC, so when the same people demand to see a list of rules that are supposedly broken the irony levels really do spike.
If we want to avoid long drawn out conversations about whether somebody is causing a problem to the group, having a list of things that we think are problems would be a cracking start. Mediation would be part of the process, and expulsion a final step. That was exactly how it happened this time, just... way more public and ongoing.
As the group moves forwards, past this rough and tricky time, maybe re-evaluating the idea of a CoC would be beneficial for everyone to avoid a similar situation arising in the future.
