Nothing succeeds like example.
I started looking around for obits to post to the boards, which of course I have gatewayed to the lists. That gets the list members interested, and I keep reminding them to post obits, deeds, etc. that they come across in their research. I think queries are self-explanatory, except that you need to remind your list members to click on the link to reply. I've had grieving list members write privately to thank me for posting a family obituary. They want their loved ones memorialized, but are in too much grief to do it themselves.
