You were removed from the guild for failing to meet the minimum requirements for two weeks straight. There was a message posted in guild chat about you needing to bring your numbers up after week 1, which you didn't respond to. Sorry but with 2 weeks in a row of not meeting requirements and two people on the waitlist, and fair warning, I don't think that's unreasonable. However, you are welcome back if you can commit to meeting the requirements, but you would have to re-join on the waitlist (I think there is only 1 person ahead of you). I suggest you post on our official thread here: https://www.trueachievements.com/forum/viewthread.aspx?tid=803894 which discussed you not meeting requirements and moving someone from the waitlist to the guild so you can be more in the loop, and also check guild chat regularly to avoid this issue in the future.
