EDIT: Have now found the answer It's further down in user tagging .... Mods if you see this please delete the thread unless you think it useful in case anyone else may search and find it.

I've set my default thread notifications to no e-mail notification but I keel getting an e-mail every time someone quotes me and can't seem to find an option to opt out listed in Edit Options

Does anyone know how I can switch this off so I only see them when I go to the site??
