So guys I wrote a clone of Slackin [0]. Slackin is written in node.js. I don't know JS and it was very difficult for me to customize anything, like adding some related links to landing page, protecting the page with captcha etc. Plus slackin doesn't work if JS is disabled in browser. So I rolled down my own version written using Flask. This is my first Flask app and I really appreciate any feedback/PR. Thanks!
