Depending on your interest and involvement in ALTA you may want to register to one of these lists:
ALTA-Announce: Join ALTA and Keep informed about ALTA news
Become a member of ALTA and receive periodic announcements by the ALTA Executive Committee about forthcoming activities and resources of the Association. This is a very low volume list of interest to language technology specialists and to onlookers from other fields. Everybody is welcome to join this list but only members of the ALTA executive committee can post messages. By joining this list you are automatically a member of ALTA and have the right to vote for executive members.
ALTA-Tech: Participate in technical discussions
Participate actively in the ALTA community, posting your language technology questions and discussing topics of current interest. This is an unmoderated mailing list of interest to language technology specialists and those who would like to learn more about language technology. This list is open to everybody but only members can post to the list. Join this list in addition to ALTA-Announce.
