I just wanted to let everyone know that the mailing digest functionality should now be working again. This required some custom database tweaks, and while I've tested it repeatedly, there still might be minor problems. If you do not receive digests you or are expecting, or do receive digests you're not expecting, please contact me at btmiller -at- helix -dot- nih -dot- gov.
Now that this is working, I am going to tackle the "favorite topics" issue. Apologies for this taking longer than expected to get finished.
