my issue was resolved (quickly and efficiently). The developers are very responsive.

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.

Here is the link to the group. http://groups.diigo.com/group/aps_21st_century_learning

Can lists be created for a group? Is this a feature that will be offered in future upgrades?

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.
