I like that it allows me to create sections of my portfolio for each subject, as well has having different themes within those subjects (i have been using this in conjunction with Moodle).
The font size can be quite small which makes reading some pages difficult at times - however you do get used quickly! It's not too expensive either so there isn't much risk involved when trying out new software or platforms etc., although they are working hard towards making costs more affordable by offering discounts/free trials /etc.. This program works really nicely together wtih moodles learning management system allowing students access from anywhere without needing internet connection via their computer; also being able to upload work directly into portfolios themselves rather than relying upon teachers doing all uploadings & marking up submissions manually would save time if we were teaching many hundreds per year!!
