Can some one help me join the Mentor Guild? I know it is by Invitations only. I don't know if I ever got a Invitations. If don't recognize email address, I just delete it. I don't know if I would make a good Mentor. I would like to making ac valhalla better. I just know I am not good at the second stage of mastery Challenges near London. I don't know if Mentor Guild is a pay to play group? I just wish I could contribute to making ac valhalla better. I am Muse2005. am 51 years old. I have psoriatic arthritis, weaken immune system, and a heart that works at 35% strength due to heart attack in 2015. I can't work and on disability.
