Moderators work as a team, and it would be great to have a team that is diverse, has broad combined chemistry expertise, and broad combined social skills. I just self-nominated for the 2022 moderator election, and I would like to encourage others "in my cohort" to do the same. My chemistry focus is a bit on the edge of things, i.e. biochemistry. So if you have been on the site for three to six years and feel you could contribute, why don't you self-nominate? If you have someone in mind who might enhance your experience on the site if they were moderator, you could add this as a comment or as an answer. I know this is a bit pushy, but without more candidates than open positions, there can be no election.
I don't think replicating what we already have is necessarily what we need, but if you want to look at exemplary models of moderation look no further than my fellow mods. Consider for instance @andselisk, who shows a stout devotion and does not shirk from any of the many moderation roles, from handling rude and abusive participants elegantly to editing posts, flagging low quality work, and commenting as necessary. Also on display are an impressive depth of chemistry knowledge and skill using moderation tools to identify and handle fraudulent use of the site. I'm glad to be in good company.
There are surely a good number of participants on the site who would make good mods, bringing their own range of skills and interests to the role. Karsten listed some in comments, who already make great contributions but may want to take on a different role as moderators. I also hope to see more apply to take on the position and encourage you to do so.
