We currently do our registration for our events with Gravity Forms feeding some constant contact lists.  I was looking to migrate that process to your plugin.  The biggest weakness of the current process we have is the onsite check-in that we have to do manually.  I see that WP Event Manager has badge printing, but the documentation is a little weak on the onsite process.  Ideally we would like to have the solution up when a attendee walks up to registration.  They give their name, the check in person looks them up checks them in and prints the badge.  It seems like your solution may support this, but I can't seem to follow that process in the demos or documentation you provide.  Can you provide any information or feedback on this?  Thanks in advance
