Well, I can browse here through the Safari browser, but everything is kinda small unless I zoom in like crazy. I've tried the Tapatalk app and it works great with some other forums. When I search for Castlevania it says something like: "Can't find the forum your looking for? Ask the forum administrator to activate Tapatalk!" ...dunno if anyone besides me would be intersted in that though, lol! Also, I don't know how its done either. They make it sound easy though!
Tapatalk should be compatible with SMF anyway, that's all I know.
