I have two things to say on this matter - that I have previously said to others that have approached me regarding either appointing or dethroning their current forum moderator:
1. If you want to demonstrate that your forum needs moderation - or that you current moderator is not managing the forum adequately - all of you need to report posts regularly.
It is the best way to objectively demonstrate to those of us that don't come into your forum that there are issues which aren't being addressed. Otherwise, we are relatively oblivious.
2. If your forum clearly demonstrates it needs a new moderator then there will be a open announcement but a private application system like we had earlier this year for GM / Non-tennis / Russian Roulette moderators.
You cannot elect your own moderator by a public poll.
The reasoning for this is that being the forum moderator is nothing to do with popularity though obviously it would need to be someone that regularly posts in and uses the relevant forum. We take into account previous poster reprimands, general opinion, look through their more recent posts etc. The person chosen needs to have demonstrated that they are willing to make unpopular decisions if necessary and they are willing to demonstrate exemplary conduct wherever else they post on the board beforehand, not at the time of the appointment.
If I'm making it look a rather unattractive prospect, that's because it is. Having said that, you do have the chance to try to make the forum run better and listen to my constant moaning in the moderator forum so it's not all bad
