OK, I must be pretty dense for I've spent about half an hour trying to figure out how to subscribe to a topic here on Trad Gang. The closest I've come is clicking on "Edit Topic Notifications", but it only tells me I haven't subscribed to any topics. Help!
to get an email notification of when someone replies to a topic you've either created or posted on, make sure you're in the 'full reply form' mode (click on that button) and check off 'Email Notification: emails sent to you whenever someone replies' before submitting your topic or post.
