There are two ways of attending an OA meeting: face-to-face and virtually. Face-to-face meetings are where members travel to the meeting location and are in the same physical space while sharing and hearing what each of the members has to say.

Virtual meetings are newer and depend on technology to provide the location/space for the meeting. Telephone meetings, online meetings, video conference meetings, and meetings that use text or social media applications are all a part of the OA virtual world.
