Thanks again for everybody's patience and understanding as we work out the kinks and communicate some of the features of the new Discussion forum & mailing list. This thread is a place to ask questions & get answers!
One question at the top of many people's lists is: How do I get digest delivery?
Answer: To manage your subscriptions, visit your "My Profile" page (either click on your name in the header bar, or go to Members > My Profile page). Under the "Notifications" tab/link, you'll see all your subscriptions listed. (If you don't have any, go to "Add subscription" to add a content type.) To edit the delivery options of a subscription, click "edit" next to the one you want to change. (Alternately, you can do bulk operations on your subscriptions by using the checkboxes at the start of each row & using the "Update options drop-down menu".) To adjust the email delivery timeframe, change the "Send interval" field to yourdesired time period. Selecting "Daily" will equal the previous digest option.
You'll see when you go to Add Subscriptions, or as you surf around the site, there are a wide variety of content types that you can receive via email. You can subscribe to individual threads (which is very handy if you DON'T want delivery of all messages but you want to engage in a post you started or care about); content types within local groups; Job posts; etc etc. One thing to know as you review the "Content types" options is that Drupal calls every bit of content a "node", so "Node type"="Coroflot job" with "Send inteval"="Immediately" means every Coroflot job entry will be sent via email as soon as received by IxDA.org.
