A Timeline of Sysops and 'Crats
(a work in progress)
This chart reflects the highest position that an individual held during the month in question, even if they only held it for one day. Some promotions and demotions are not indicated by the chart, such as if a sysop requested a demotion in one month and was re-promoted the very next. In such a case, it would appear here that they had enjoyed an uninterrupted term as a sysop, when, in fact, that would not be the case.
*Demotion records appear to be missing from the user rights log for this user; any information would be welcome
