Since there is no universal global http://myflightsbird.com]list of the community members, the use of a random sampling approach to sampling from a list of all the virtual communities is impossible. Thus, use a convenience sampling method. However, there is a need to develop a criterion to ensure an active member of the community is included in the sample. There is a need to establish member stability and traffic volume. The inclusion and exclusion criteria will eliminate the inactive communities, particularly in a community where the communication is through announcements and new postings. For instance, a snowball approach can be used to identify the respondents based on the objective of the study that intended to study an active virtual community member from a particular geographical area participating in an online discussion.[/COLOR]
