Every congregation has a different "body of elders" each is different, you could send five letters to my kingdom hall and they would head straight for the super shredder. Drive fifteen miles and their "body of elders" could accept your letter with "one" or "two tries". Super Righteousness Kingdom Halls are going to test your endurance and humility, Moses waited forty years to get back into the Congregation of Isreal, be patient and keep you head up!
On a serious note, adultry under the "old school thought" was a minimum of two years, others felt five years was justice. Who is denying your letters to get back in, no letters came past me over the last three years although I enjoy when you beg and plead and rub the dirt off my high heels with tears.
