@Edent so, I strongly recommend looking at the full Activity Vocabulary. There are several activities specifically for check-ins. I'm excited about this project.
@evan Thanks Evan, I really appreciate that!
I've got the bare-bones working. I can now post a location. Let me know if you want to take a look at the account.
@Edent I'll put it on my list! I've got a deadline for my book on the 31st and I'm trying not to get distracted. I'll check this week. The big thing is: use `Arrive` for check-ins! And include a `summary` for servers that don't know what to do with them.
