You can write about anything that you like on your blog - a great night out, an idea for a project, or your favourite food! However, you must bear in mind that the University has strict regulations about the use of computing facilities, which all users are required to accept before they are assigned a IT Services username. They cover authorisation, copyright and defamation. Disciplinary procedures are in place to deal with breaches of these regulations. The regulations incorporate conditions for acceptable use of the national academic IT network, JANET. There is also a code of conduct that covers use of the public work areas and connection to the campus data network.
For more information see the Warwick Blogs terms and conditions.
Also note that your blog is not an official means of communication with the University or any member of the University. If you wish to discuss something with your tutor or the counselling service, for example, you must get in touch with them via email, telephone, or in person.
