My name is Marian Moraga, and I am a member of the Alarcos Research Group at the University of Castilla-La Mancha, Spain. We are trying to develop a quality model for Grid portals but we need your opinion about the quality characteristics that are relevant to Grid portals. We would be very grateful if you would answer the questions that you can find in http://alarcos.inf-cr.uclm.es/per/mmoraga/survey.doc. It is worth emphasizing that your answers are fundamental to the success of our work. Please, send me an email with your answers as soon as possible. My email is MariaAngeles.Moraga@uclm.es

Thank you very much in advance for your kind cooperation.
