Nice, but: can you please stop doing that?
This generates a lot of messages on most days. Like I saw 330 on April 6th, 463 on April 19th, and a whopping 603 the day before yesterday. And this will only increase when the number of people testing gateways increases. This single Slack channel really hurst the 10,000 Slack message limit, which includes all Slack channels and private messages. So: messages in all channels are removed much earlier if one channel posts many messages.
Maybe get a standalone Slack account for just that?
