Content management 1 Web site –url is www.materrsc.org/course/home.htmlwww.materrsc.org/course/home.html –Username is stat –Password is mrscsc2006 –Note : username and passwords are all in lower case Important pages –Home page : all other pages are linked to home page –Notice board : show all updates, changes to content –FAQ : additional questions and answers
15
Content management 2 Download of contents to your computer –Each page can be saved onto your computer Programs are java applets in a subfolder applets Graphics are gif files in a subfolder pics –All contents are in a file called statcourse2006.zip Course home page contains a link to the zip file You will need winzip or similar program to unzip the files Updates and changes –The notice board will record any changes to the contents –Bottom left corner of each page will have version number and date of last change
16
Content management 3 Tour of the web site –url, username, password –The use of hidden contents –The use of computer programs on applets –The use of ctrl + c for copy and ctrl + v for paste Home page –Links to other pages –Contact sessions –Course coordinator and tutors Notice board : architecture FAQ : how to use
