Hi!
I have written a Slack App that renders PlantUML diagrams in Slack channels.
I wanted to give something back to the developer community and so it is completely free (my hosting costs are funded by other apps I've written for other platforms) but so far has only had me putting it through it's paces.
I'd really appreciate it if people who use Slack could give it a spin and give me feedback so I can make it better for other people's use cases as well as my own.

Many thanks in advance,
Terry.
