Thanks Vincent - I've tried to respond to your questions below. Thanks for your reply.

> do u mean when u share a bookmark to a group, you'd like to know whether this group is created/managed by you or not?

-- yes, i that's it. when i share a bookmark, and click "share to a group", i'd like a way to differentiate the groups that I manage/created verses the ones other people do. I have about twenty groups or so and half of them I started. I feel more confident adding a lot of bookmarks to the groups I made and want to only share "creme of the crop" on other people's groups...

> we design active group/list feature to solve this problem: i have lots of groups/lists, but sort of them i'm willing to share stuff to. those groups/lists we called active groups/lists.

-- I think I get what you are saying. I can archive groups that I don't post to and keep the active groups ones I post to... Right?

> we restrict user share stuff to a group once a time for anti-spam

-- Makes sense and I sorta figured there was a good reason for it. Thanks for explaining.

> FYI: you are welcome to post your topic(idea, request or bug related) at Diigo Community

-- is that the preferred place for an idea over this group?
