Increasingly, citizen scientists do work beyond the primary goal of the project coordinated via the discussion board. These activities often take place in discussion boards and have a set of terminologies norms for contributing. For newcomers, learning new terminologies presents a challenge since there are no formal opportunities for them to learn the terms and volunteers who join later need to learn more than volunteers who join earlier in a project life-cycle. In this poster, we examine how newcomers terminology uses shifts over the course of two citizen science projects. We find that, although, newcomers joining later might face obstacles, terminology use among newcomers associated with advanced work increase over the project's life-cycle. The analysis can help the science team assess whether newcomers on the talk page have either adopted advanced terminologies and if they need to have a more formal resource such as tutorial or blog posts.
