If you are running a WPMS blogging network, the issue with most login widgets that you add to the main site’s sidebar is that it doesn’t pull the user’s own blog info. That is why the WPMS Sidebar Login Widget was created. Instead of the user trying to remember the login page of their own site/blog, when a user logs into your main site, the user can conveniently navigate to his/her blog by clicking the Dashboard link. Try it out and let me know how you like. If there are any bugs or issues, please feel free to let me know about those as well. Click here to download the widget.
