Hi Cathy,
I have a couple of bugs and/or feature requests to report.
1) You should be able to make a bookmark private when you add it, you should not have to edit it to make it private.
2) I don't think we want to reveal our email addresses to unregistered users. As of now they can view public bookmarks, click "details" and see it.
3) The index page should be templated, IMHO. It's hard to tell if this is fixed or not on your version since there is no visible template 😊
Thanks for making this useful package even more so!
