You can now tag friends within the comments or on the actual check-in!
1. In the Check-in details you can select the "Tag Friends" feature to the right underneath adding comments
2. Next, select the friends you want to tag - and then "Done"!
3. You can also tag your friends within the comments section for your check-in. Simply start typing "@FRIENDS NAME" and then you can select the friend you wish to tag.
When you tag a friend in a comment or check-in comment, it will notifiy that user in their notifcations tab, and push alert (if they have enabled it). Tagging a user a check-in, doesn't check-in the other in - it just tags them in your post.
You can only tags people that your friend on the service.
