The aim of this masters thesis was to study how the members of a small non-profit organisation perceived the web forum, compared to the other information channels of the organisation. The organisation was defined as a virtual community. A literature review was conducted. The theory construction was based on the sensemaking theory. Interview questions were constructed based on the literature review and the sensemaking theory. Ten members of the organisation were asked to participate in the study, of which six persons agreed to be respondents. The result showed that respondents do see the web forum as the single most important information channel when it comes to information exchange. In several different situations, they perceive information needs, seek for information and make use of the information as long as they do not perceive too great barriers. Another information behaviour was also noticed: usually the respondents do not seek specific information but discover relevant information by chance. This could sometimes be information that the respondent did not know he or she wanted until it was received. However, the respondents also consider other information channels in the information system to be important, especially meetings in real life. The thesis concludes with reflections of the research done and propositions of future research.
