To become a citizen of TWC you first have to meet the qualifications. These are set pretty low and it's not a case of everyone who meets these gets the rank automatically. To qualify for Citizen, a member must have at least fifty posts, been a registered member for one month, and have no warnings within the last six months. Non-point infractions or 'notes' are not factored into this.
Above and beyond these basic standards, the rank is then awarded for contributions. So if you think you make a valuable contribution to the site, chances are you're citizen material.
To get promoted you have to be patronised by an existing citizen. There are two ways this can happen. The most common is for a citizen to notice your contributions and send you a PM asking if you'd like the rank. If however, you think you are worthy, you don't have to wait to be noticed! You can PM a citizen directly and ask if they will sponsor you. Only those citizens who have themselves held their rank for 3 months can patronise.
If you get asked, or a citizen agrees to patronise you, you then have to write a short paragraph explaining why you want to be a citizen and why you think you are worthy. Keep in mind that the better you present your case to the CdeC, the more likely you will be considered citizen material. Include links to your most worthy contributions, be they modifications tools or work, or well-composed debates. PM the paragraph to your patron; they'll add their own comments and PM both to a member of the Consilium de Civitate. The CdeC will then take a week to discuss and vote on you. If you get 60% of the non abstaining votes, you'll receive a PM from the Curator congratulating you, and have your rank, a shiny new badge, and all the privileges of being recognised as one of TWC's outstanding members!
If, for whatever reason, you should fail the vote you must wait 1 month before you can apply again
