Right now, MK promotes based on voting by the three leaders. We each look at our own candidates individually and decide if they are responsible and knowledgeable enough to be councilors. We've had more than a few people join up, asking for position, usually before they've even been accepted.
Our response to this has always been this since the new leadership has been in place, if the person shows they are responsible, active, and knowledgeable (by our standards, not by reputation standards), then they are promoted.
During the time that MK was actively promoting anyone who joined, I was highly inactive, and my former priestess Ferrum was as well. We had moved the coven off the site, which in the end turned out to be a mistake. I came back, Ferrum told me to do as I wish. I did the everyone as council bit for the following reasons:
a) I was still highly inactive.
b) I was curious to see if a Spell Casters type coven really would work if there was someone governing it.
c) No one I thought could handle it was around for promotion.
A few of my members started wanting me to become active again, fully active. They asked me to fix the coven back up to what it should be. So I brought Belle, who has been with MK the whole time, into the leadership with me to help me out. Belle and I brought back the old members who we actively knew, and then together we decided to get Chenny to join us.
Each of our councilors now has contributed to the coven and the site, either currently or in the past, many of them are also our teachers.
