I'm interested in helping you! I have been working hard at my job and simultaneously having a busy social life, so I haven't had time for WoW. I'll keep the github notification emails about this in my inbox to remind myself that I can help someone when I get the time. Thank you for your patience!

Thank you so much both for reply and your interest in helping ^^ !
