BuddyPress Clear Notifications is a simple BuddyPress plugin which allows users to clear all the notifications in one go. It simply adds a "Clear All Notification" link in the notifications drop down menu. It marks all the notifications as read.
Here is a screenshot.
We developed this plugin on the request of one of our members. We are making it available for you and hoping that it may help you while building your site with BuddyPress. Let us make the BuddyPress experience awesome.
