www.diabetes.co.uk would be the address to type in to your internet browser address bar........
you can then save that link as a favorite.........or you can navigate to the forum itself http://www.diabetes.co.uk/forum/ and save that as a favorite, that way it just the click of a button....
what browser are you using, Internet Explorer, Google Chrome, Mozilla Firefox?
There is an app you can download for your tablet .. It should work on a desktop .. Think it's on the home page .. Hang on I will have a look .. And get back
you will see a star on the right hand side of the address bar, click that and you will then be asked where to save it and by what name, save it to the bookmarks bar, which will then show as a button underneath the address bar......
Sorry it's for tablets and phones .. So your best bet is to save it as a bookmark .. Now I did say I am a Mac user .. On my desktops I can drag the address from the browser bar into my screen and it will stay as a link I can just click to activate ....
