The SWUUC maintains a list of DREs. It is swuu...@lists.uua.org However, as a non-member, you cannot post directly to it without approval of the list administrator. The easiest way to post is to either ask Sheri Phillabaum post it or to ask Jennifer Nichols to post it. Sheri is on the list and Jennifer is the administrator.
For the ministers, I expect that the SWUUC maintains a list for them as well.
Or the UUMA Chapter certainly does. I don't know the protocol they have for postings to that list, though or whether postings from UBarU would be welcome. My guess is they would NOT be welcome and we should assemble our own list.
The best way I know to assemble our own list is from the SWUUC website. If you go on the SWUUC website there is a directory of churches, and it has contact information there.
I've done this before when I was doing mailings as the SWUUC treasurer. There are 75 congregations, so it's a project of a half a day or so to create or maintain the list. I found it useful to cross-check the SWUUC info against the individual church websites.
Hope this helps.
