Many Internet users join so-called user forums (discussion groups, listserv etc.) for acquiring help with technical problems concerning computers, software, or consumer electronics. In cooperation with students, I analyzed a number of these user groups to figure out how this form of reciprocal technical support works in practice. A first study focused on the content and phrasing of the help question that forms the start of a discussion thread. We discovered that in addition to an often very elaborated description of the problem, rhetorical elements play a role, such as credibility, justification of the help request, and politeness.
