My overall experience with edmodo is good. They give quick response + cool swag + lots of input fields to test.
This time it was not planned. I was trying on many programs. Suddenly I opened edmodo and this time it redirected to new.edmodo.com. I posted my xss polyglot (as described on my first write up #540a33349662) on created school. This time I posted payloads on poll. Then I clicked on my dp to open my profile and it redirected me to www.edmodo.com/* . On this domain, there was some notification. I clicked notification and boom. It’s there.
