Basically, though, ALA has four rooms available for groups to use – two 25-seat rooms, one 50-seat room, and one 100-seat room. Because these are virtual spaces, they’re available 24/7. Any ALA unit (divisions, round tables, sections, committees, etc.) or ALA-affiliated group can use a room to hold a meeting (following existing ALA bylaws for meetings), a discussion group, or as a presentation space for up to 100 participants. OPAL rooms provide:
- Text chat (including the ability to save the transcript);
- Voice chat for participants with microphones and speakers (including the ability to record the conversation);
- The ability to display web pages or slides for presentations;
- Co-browsing web pages;
- The ability for participants to ask questions via text chat.
