// since the last request (this protects the founder from
// being bombarded with frequest requests)
// - there's an active request older than 90 days

// An email is sent to the founder (Y).
// The request is "active" (ping_user is set to X's ID)
// - If Y declines the change, an email is sent to X,
// and the request is cleared.
// - If Y accepts the change, an email is sent to X
// and the request is cleared.
// - After T + 60 days, X can become founder
// - After T + 90 days, new requests are allowed even if there's
// an active request, i.e. after the 60 days elapse X has another
// 30 days to assume foundership before someone elase can request it
