Hi Pros,

I would like that here on WPMUDev Community is an plugin like this:
http://codecanyon.net/item/wordpress-user-bookmarks-standalone-version/6584179 is in the privat page from us.
so we, as your members can bookmark any content they want, posts, forum topics, custom posts, and also manage their bookmarks into collections.

This would help to sort all the posts there be interesting but not for now, so we can it easy find later!

Thanks Manfred
