James,
I think that the browser you are using could be useful information for Asher, for the moment the one that can be presumed is Safari.
Did you try different browsers?
Feedback from my side:
I am browsing the forum with Opera on a Symbian Belle Smartphone - no issues despite the poor resolution by todays standards.
The other device I am using is an Android tablet (currently 4.1.1) with Firefox (I am posting from this device right now) - no issues.
There is one thing that could make it a little more tablet-friendly: larger surfaces for the buttons and links.
Surprisingly this is no issue for me on the smartphone as the relevant parts are magnified on the first click making it easier to hit the desired one.
I am pretty sure that there is an option that can be switched on for this forum that adapts the layout to mobile devices, but this is something that only Asher could tell.
Did you compare to other forums with this option enabled?
Best regards,
Michael
