Check-In plugin allows users to post statuses with check-in ability to specific locations. It will display a status with a map of that location. It’s also integrated with the business module. So while people check-in, they can select a specific business instead of a location. When members check-in, they also can `tag` any friends on the social network who are with them, essentially letting other friends know that the person is there, too. It allows to include a photo which is supported by the wall.
+ Check-in for a specific location
+ Check-in for a specific business
Note: can’t check-in and post a colored background status at the same time.
Importance: this plugin changed core files so that be carefully when installing if your site has been customized.
