Tapatalk is not under the control of RpNation, as GgAcE already said the mobile version of the site has everything you need. And RpN no longer supports Tapatalk. So, yeah.
Thanks @Hunnyhelp - You are correct. Tapatalk is a "general" uncustomized application that has no relationship with our forums. They are an "out of the box" system & do not allow other sites to have custom benefits. They are strictly focused on making forum posting easier. They don't care about the other stuff.
Please try our website on your local cell phone browser. We have a neat mobile theme that is automatically detected & does support groups, the shoutbox, the character gallery, etc.
