Our update today has introduced some nice new features: better handling of friends functionality and a possibility to change the tags of several bookmarks or BibTeX entries in a batch.
On the page /friends you see all posts which are set "viewable for friends" of users which declared you as their friend. Furthermore you see all your friends, can add ore remove them and you see users which declared you as their friend. More on this is written on the help page. Don't hesitate to ask, if you have questions on this.
Thanks to the suggestion of one of our users we have added an easy way to edit tags of several posts at once. Just click on the "edit" link between the "next" and "previous" links on your myBibSonomy page. Then you can edit all tags of the posts (bookmarks or publications) you've seen on the page. As this also works for your tag pages, you can now complete all your imported BibTeX entries which still have the tag "imported".
Some weeks ago we improved and unified the settings for the tag cloud. If you have JavaScript enabled you see now above your tag cloud the options for sorting (Which could be either by frequency (i.e., how often you used a tag) or alphabetically.), layout (You can choose between a cloud or a list.), and minimal frequency (Allows you to show only tags which you used at least that often.).
