The site is well organized with more than seventeen categories of “tools” ranging from Presentation Tools, Collaboration Tools, Audio Tools, Music Tools, Converting Tools, Image Tools, Research Tools, Mapping Tools, Quiz and Poll Tools, Graphing Tools, Creativity Tools, Video Tools, Slideshow Tools, Drawing Tools, Writing Tools, Widgets, etc. I did not find one link that did not work and the pages were all very nicely linked for moving from page to page
