One of my XenForo forums deals with Windows Phone 7 devices. I have it set up to support Tapatalk. They don't have an official client, but there is an app called Board Express that supports Tapatalk. Now, here's where things get tricky. The Windows Phone Tapatalk forum app Board Express does not support XenForo. I've been in touch with the developer and he's indicated the following as a problem. I'm not a developer, but was hoping I might be able to offer him a solution based on feedback from developers here on the XF forums. Any suggestions that I might be able to pass along?
