Currently we don't offer Automatic importing of Service Hours, Miles, and Nights for all types of troops. However you can easily enter this for each individual user.
Go to their profile by clicking on their name. We're going to use this fake account as an example
Go to the Participation tab and press Record Outside Participation.
Fill in the box with the Hours, Miles, and Nights that you wish to record. In this case we're only recording for the year of 2012, but you can do however many years that you want - you could even say "Imported Activity" if you'd like. Just make sure you save when you're done.
Now the record will show up under their participation tab and you'll see that their account is showing the updated information.
And that's all folks! :D
