WordPress Multisite network administrators will love the handy new WPMS Sidebar Login Widget plugin. It pulls the user’s information and puts his blog info in front of him after he logs in.
The advantage of this login widget is that the user doesn’t have to try to remember the login address for his site. Once logged in the user will have links to his own dashboard, new post page, and profile page.
The WPMS Sidebar Login Widget is available for free from the WordPress plugin repository.
