I downloaded the IP.Board app for my iPhone to access this forum and it's a terrible. It's so terrible that many users tried to login on the home screen with the CORRECT credentials which left 2.5 stars on the iTunes App Store. Tapatalk is a mobile version of the Internet getting on forum pages that have the Tapatalk extension installed. My clan's forum has it installed ans it's VERY easy to create account for each board. In addition, I'm also a forum moderator there and I can still edit, lock, delete stuff at ease. I saw something on their site that IPS boards are compatible with said app. If it is, I would encourage you guys to check it out.
