Hello, I'm working on implementing an ActivitiesService for my SNS and I've come across this line:
// TODO: Validate the activity and do any template expanding Any suggestions on how to validate an activity, or do template expanding. I'm especially interested in template expanding because I have a gadget I've written that is using it. I've looked around the Shindig PHP and noticed several references to Substitutions and such, but wasn't sure how to access any of that from the ActivitiesService class. Thanks, Brandon -- Brandon Peters
