Tapatalk is an application to allow access to Internet forums on mobile devices. Just search for Tapatalk on your Android or Apple device, install and open it, search for Skyblock in the search bar, and login with your forum credentials, and you are set. You might be required to create an account on Tapatalk to use the application.
Also, if you want to get rid of the "Sent from my __ using ____", go to Settings and tap "Edit Signature" under the General section. You can choose to have no signature or a custom signature if you wish.
Mostly uses my computer, since I'm grounded from my phone. ;_; But when I get a chance to, I'll download it.
