Users may request on my talk page that I should stand down.
If 3 users in good standing, or 2 admins, request my resignation within any period of 61 days, I will stand down, and submit a new RfA. Rather than set prescriptive criteria here e.g. so many edits in a recent period, I will decide what constitutes good standing, although the main point is to check that they do not seem to be sockpuppets or trolls.
I won't submit more than 1 RfA per 3 months.
If I refuse a reasonable request, any user may request (link) that my tools be revoked without me volunteering. That way, I cannot simply avoid the recall. Link to this page and a diff showing where I refused. I trust the steward involved to decide whether my refusal was appropriate or not.
