I found an alternative solution called mobile upgrade, and it doesn't even require you to install an app !!
So on your mobile device simply browse to the forum www.yamahar.co.uk (on an iPhone do this using the safari app)
In the top left hand corner of the screen you should now have three horizontal lines with a blue or green dot, click on that

Now click on get a better experience, and it will step you through how to add the forum icon (Yamaha logo on a red background) to your phone's homepage.

This is the generic images the software developer has for the iPhone and Android screens.

I think this can also be installed on MacBook, if anyone is interested in that please PM and I will investigate and add instructions on that too.
I think this a really good solution for the forum on mobile devices, let me know what you guys think.
