There are many specialized mailing lists for Texas researchers.
Many counties have their own lists and there are several Texas regional lists available.
BUT , you are responsible for not going too far off-subject. If you stay on-subject then most of your responses should of interest to the whole list. Personal , by replying only to the sender. If you think something questionable but might be important enough for the whole list to receive, send it to me and I will consider forwarding it to the list. I reserve the right to remove anyone who is detrimental to the purpose of this list.
