Hi Irulan,

We are looking into Tapatalk. The 4.x versions of VBulletin also support a "mobile" stylesheet for the forums, and even a vBulletin forum "app" - (but that has some ongoing costs for Apple developer licenses and app store fees).

Hopefully the mobile-optimized stylesheet will work well. We are planning on upgrading to the 4.x version soon (we're a year or two behind the current release).
