For example Mahara claims to be an online portfolio creator - but you can also build your CV with it [1].
I just wish someone would come out and say "this is the format your resume/CV should be in" - not just for my own sanity but so that when applying for jobs. A lot of companies now they have their crappy resume reader that attempts to read your resume into normalized text boxes - and usually fail miserably forcing you to retype your resume.
