This weekend we are making some significant changes to the website. You will notice that a great many more of our articles are appearing in a new look and that the navigation bar at the top of the page has changed on a number of sites. Our web address - theguardian.com - will become the title piece on the front page and replaces Guardian Unlimited. This is the latest phase in transferring the whole of theguardian.com into a new system and design which will help us continue to produce the very best in online journalism. From Monday our news, politics and Observer sites will be appearing in a new format.
If you use our site regularly you will already be familiar with the improved layouts and bigger pictures, as well as the helpful 'keyword' navigation against articles, which tie into the look and feel we gave our homepage back in May 2007. The size of the task, which involves moving half a million pages into a new format, means that while the majority of the work will be completed over the weekend you might notice some irregularities over the coming week. Our sports, arts, life and style and education sites will also be moving over in the next few months.
We appreciate any feedback you have - particularly if you are experiencing difficulties finding your favourite pages and sections - and as ever all views from users of theguardian.com are always welcome.
