There are two mailing lists for the UDL Curriculum Toolkit:
The UDL-Toolkit-Announce list will send out occasional updates about the project, new major versions of the software, and news. Generally this will be no more than one message a month. Subscribe or edit your subscription to udl-toolkit-announce. You may also look at the archives of the announcement list.
The UDL-Toolkit-Developers list is a discussion list where any interested software developers can ask questions and get help in using the Toolkit. Any member may post to this list to ask or answer questions, so the volume of messages may be higher at times. All messages to the announce list are also posted here, so there is no need to subscribe to both lists. Subscribe or edit your subscription to udl-toolkit-developers. You may also browse the archives of the developers list.
