As the person who does the cross posting to Facebook, I get only the aggregated email message, not individual messages. This does cause me to not get timely postings of BX/SX lists, but it saves wading through dozens of individual emails each day. Usually by the time I post to FB, the seed and bulb lists have been out for 12-24 hours. If you think you have missed messages, you can check the List online on the PBS website. That’s the most reliable way to know what has been posted to members. Kathleen South Coast of Washington, zone 8, or this year, 9, warm and dry.
