I have trouble with #1 above also, and have for a while now. Sometimes my lists are there, and sometimes they are not, as if I had never created lists. Just some dashes appear and I cannot add my bookmark to a list. I'm just about always on Firefox.

I have a student group, and in the teacher console, if I click on "activated" members, none are listed. Yet, several have successfully joined the group and uploaded the toolbar, and one has begun to share bookmarks.

I have a class working through a Diigo education account. Sometimes sticky notes appear and sometimes they do not. I think the same is true of highlighting. It varies from time to time, but also between screens when I am viewing the same person's work in two places at the same time.

Very confusing in trying to give credit for their efforts.

This has happened a lot, but here's one:

Here's an example of how things appear differently in different pages:
This is what I get when I go to a student's own page from the teacher console:

Lots of highlighting, no sticky notes.

and this is what I see when I just go to the bookmarks from the whole group:

http://www.screencast.com/users/amlusch/folders/Jing/media/1ac5cca4-f63b-4610-ad71-99f60f314f9e

Here her sticky notes appear, but most of the highlighting does not show up.

Thanks,
