I have been, actually trying to setup SteemWatch, you mentioned, but I need to set up Incoming Webhook through Steem Slack. I click on Steem Slack link there but I can't seem to be able to register atm as it says "Application Offline for Maintenance".
Btw, have you thought about making guide for activating this webhook. I don't think there is any proper guide there. I found this one but it doesn't give proper instructions, just copied screenshots. I could do it myself but I'm an awful writer. I just hate writing unless it is an expression of my opinion.
