I found this link from Allison Miller and Eportfolios Community of Practiceon my Facebook account. I think it is time for me to learn Mahara! This service limits file storage to 50 MB. But I will be using my cloud storage for all on my artifacts. It will be interesting to try out this service.
I guess there is another free Mahara hosting service, Foliospaces which offers a Premium upgrade for $40/year (up to 2 GB storage).
