P2 is a very popular WordPress micro-blogging theme with an increasing number of add-ons. Ryan Imel recently created a new plugin called P2 Check In that adds “check in” capabilities to the P2 theme. It comes with a “Who is Checked In” widget that you can add to your sidebar.
The P2 Check In plugin also adds a “Log In/I’m here!/I’m leaving!” button to your P2 theme’s header, making it easy for users to check in or check out.
This plugin can be very useful for coordinating team members, online meetings and collaborative sessions. Download the P2 Check In plugin for free from the WordPress plugin repository.
