In terms of lesson design it's best if content is organized and consistent. Our previous learning management system allowed us to hotlink URL's to small graphics (think clipart) that were embedded in each lesson. For example, if we needed to link to discussions from a lesson we could do it via a small clipart of two talking faces. The current embed codes that Populi uses don't allow me to control where the link goes. It just goes to a bigger version of the clipart. Thanks.
