thanks for the tip, not sure how to delete my avatar (which is the default group image). I only have the option to upload a .jpg or .bmp. I read on another post that the size has to be less than 200k, I've scaled down my image with no luck.
I'm coordinating an aggregation of research and the list function would help bring some structure to the group's efforts. For my personal bookmarking, the lists give me a structure to group bookmarks, I was looking for the same functionality for my group. Tagging provides the structure, lists would help define the overarching themes.... thanks for the quick response.
