We would like to thank the following retiring Co-Editors for their outstanding efforts in ensuring the quality of the Journal of Theoretical and Applied Electronic Commerce Research publications: Joan Cooper (University of New South Wales), Paula Swatman (University of South Australia). Joan and Paula have completed a two year term and due to new academic commitments they have vacated their positions as co-editors, but they will continue as valued members of the editorial board. Joan has taken a new position as Pro-Vice Chancellor (Students) & Registrar at the University of New South Wales. Australia. Paula has vacated her co-editor role to devote more time to other commitments in her current appointment. We thank Joan and Paula because they were initial editorial board members of JTAER and their previous work in collaborative electronic commerce technology and research inspired the creation of our journal.
