I really like the daily email digest of forum postings. I find it much faster to read through the postings as opposed to constantly clicking links in and out of various discussion threads. When I find something to comment on, I can click the "see in context" link to go to the discussion thread and add my comments.
However, I haven't found any way to subscribe to a forum until I post to it. If half the class has already posted before I submit my first post, then I will never see those posts in the digest. Is there a way to subscribe to a forum before I've posted in it?
