From the ALA website:
The ALA Virtual Membership Meeting 2013 (VMM13) takes place on Wednesday, June 6 from 3 p.m. – 4:30 p.m. (Central time). Registration is now open and and continues through the start of the meeting on June 6. The interactive web platform used for the VMM is limited to 1,000 participants, so pre-registration is required.
Also see the ALA Connect Member Group for complete VMM13 information and to participate in pre-meeting discussions and to exchange perspectives, ideas and opinions with both old and new colleagues and friends.

I am very happy to Chair the ALA Committee on the Membership Meetings and work with fellow ALA members to contribute to the development of the virtual membership meetings.
