== Good article processes == 

 As you're already aware, "GA" on Wikipedia typically refers to a "Good article". To obtain this quality rating, an article must be nominated at WP:Good article nominations, or GAN, where it is reviewed by an uninvolved editor. Given the backlog on the page, nominations can sometimes sit for a while until a reviewer comes along. The reviewer compares the article to the Good article criteria and will either pass or fail the nomination. Should an article degrade over time or the passed nomination is contentious, editors can place the article up for reassessment at WP:Good article reassessment, or GAR. Depending on the reassessment discussion, the article will either retain or lose its GA status. To further add more to digest, there are also Good topics, which are collections of Good articles that are within the same scope. 

 You'll see these terms pretty regularly at the VG project because many editors there try to bring articles up to Good quality, partly as a badge of honor, but also because review by an outside party ensures that quality is actually there. Hope that explains everything. If you have anymore questions, please let me know. (  )
