MyBB Community Forums

How can I make the forum easy to view on a phone? Like when you put in the website code www.example.co.uk/forum it realises your on your mobile and connects to www.example.co.uk/phone/forum

So it comes up as a mobile website

or try tapatalk

GoMobile, the MyBB mobile theme.

Does anyone have this for their forum? How good does it work?

Install it. Enter from a mobile phone/ use a web emulator for that. See for yourself.
Like it -> keep.
Not like it -> uninstall.
Completely free.

I have it running, GoMobile is in my experience the best plug in out there for mobile web compatibility.

I use Bluestacks to see the results.
It's an android emulator for PC.
