Having managed the implementation of ePortfolios and Mahara at UC since the end of 2010 it is very encouraging to see the growth trend over these years. A highlight on the following cumulative tally of user accounts graph is the kick at the end, where usage is user driven not course driven over the 2013-14 break.
It should be noted that at the end of last year we added a link to the environment from the main university web page. This delay was on purpose, it was so that we had time to establish a sizeable Mahara knowledge base and support resources on campus before advertising availability to the whole institution. Looking back it's a useful strategy.
