Not sure why but I get an e-mail notification as soon as someone has posted ANYTHING at the ThemeForest forums. It’s flooding my e-mail. Please make it stop.
Go to that particular thread and unsubscribe to that thread.
Hi DM, my best guess is that you’ve accidentally subscribed to a forum thread. Click on the e-mail reply and it should take you to the thread of origin. Once there, simply click unsubscribe. Good luck.
Edit: laranz beat me to it. Cheers.
