Forum is not sending emails on new issues or project comments

Encountered at http://www.igorexchange.com/node/8274#comment-16799 and just tested at http://www.igorexchange.com/node/8363.
So I have to explicitly subscribe on my own projects? I was not aware of that. Thanks for digging into that.
so it turns out I wasn't subscribed to the issues on half my projects... Hopefully that hasn't been an issue.
