ACollab is an accessible, open source, multi-group, Web-based collaborative work environment. ACollab is available as a work groups addon for ATutor 1.4+ , and as a standalone collaborative work environment that will run on its own. ACollab is ideal for groups working at a distance developing documentation, collaborating on research, or writing joint papers, and ideal for online educators who wish to add group learning activities to their ATutor courses. A demo and download are available if you want to learn more. Or, read on for a list of ACollab features.

ACollab Features:

    Document Drafting Room: Group members can work within a Web-based document versioning system, collaborating on document development and publication. Documents developed in the Drafting Room can be transferred to the Shared Documents Library once finalized.
    Shared Documents Library: Group members can submit documents to the library, from which other group members, or public members, can retrieve those documents for viewing or downloading.
    Events Calendar: Events can be posted to the calendar by all group members, to announce activities, meetings, due dates, or other group related happenings.

    Multi-Lingual Interface: Language can be modified by system administrators, or new language packs can be created using the ATutor.ca translation tools.
    Accessibility Compliance: Group member, group administrator, and system administrator tools are all compliant with international accessibility standards (WCAG 1.0, Section 508 US) so people with disabilities can participate fully in collaborative and administrative activities.
