Are you running a mobile friendly site?

My forum is Tapatalk enabled which lets users access it from their mobile devices. Many forums have similar capabilities.

I have been using my tablet once in a while to check on my regular forums. Most are mobile friendly except 2. The first one invalidates my password, always giving me a message that I had entered a wrong password. The other one couldn’t give me the body for a new thread. I can only reply to the post but I canno make a new post. Obviously, they are not mobile compliant and with that, they are surely losing some traffic. What if I cannot use the computer for the day? That means I couldn’t go to that forum.
