oh and hey, you can still post so its not like you were banned or kicked. i think you just need a user group. have you tried asking a section leader about this? im not sure you even needed to post in there... dont quote me on that though
yeah i just read your story... seems like you were just inactive and got left behind... hopefully there wont be any issues for you. some generals just do that to clean out their lists. i have a few people who have been inactive for almost a year but they msg me every so often to let me know whats up so i guess it just depends on the general who made the decision to kick you from the user group. Give it some time, im sure it will work out in your favor.
have you posted in the Grass is greener forum? i must admit ignorance when it comes to the whole getting back in deal other then posting there and awaiting your fate.
