Tonights #TuskPHP contribution:
Implementing a show post endpoint, some refactoring, and finally the command to send a reply to a post:
https://github.com/AndrewFeeney/tusk/commit/67b0c44f0022627cc9bd59e2b8b7926ab563ee31
_In theory_ if this was deployed to a domain secured with TLS it would be possible to reply to posts with this command.
I haven't tested it though because it's late and I've run out of time to deploy it somewhere. Maybe tomorrow ...
