The ability for employees in different locations all over US & Canada/World Wide Web access courses without having their own course instructors or classrooms was great! We have been able use this tool at our University as well from remote offices across North America with no need of physical classroom space required!! This has helped many students learn new things about web accessibility which they did not know prior but now can apply them towards building better websites accessible via screen readers using HTML5 tags etc..
I disliked one thing it took ages sometimes before we could get answers regarding queries posed online or any issues related to website design such us how does my site look like when accessed thru mobile devices? How should i go ahead solving these problems so users do enjoy good user experience while navigating around sites built upon WordPress CMS platforms??
