Hello,
Is it possible to unsubscribe from a thread/deal from the deal's page directly (ie without going to my account). I find if I comment on a popular deal my inbox gets smashed with all the replies and it is a little clunky to have to go to "my account" to unsubscribe.
Yes you can. There should be an 'Unsubscribe' link just below the 'Report' link at the very top of the original post. If you're not subscribed, it would show 'Subscribe'.
