We've just activated a mobile optimised theme for the forum on a trial basis to gauge people's reactions/thoughts.
If you are browsing on the desktop you will notice no difference, or if you have set your mobile browser to appear as a desktop browser.
If you are using a mobile browser (on any of the major mobile platforms), the forum will automatically switch to the new mobile theme, with a link at the bottom of the page allowing you to switch back to your regular theme if you want.
This trial is taking place as part of an ongoing effort by the forum administration to improve the experience for small(er) screen devices.
