Bulk Subscribe to Forum Threads?

Hi,

I’m interested in being more informed on the discussions in the forum, but I don’t want to subscribe to every interesting topic one by one. It would take me too many hours to look through them all. I’d rather to be able, for example, to just get an email alert every time someone posts something to any topic in the General Discussion or in the Responsive Shop Theme section. Is there any more efficient way to get alerted when new postings have been made to the areas that interest me?

Thanks, Jennifer
